How much experience needed?

If you want to play team multiplayer games I'd recommend that you try more difficult single player games first, perhaps a 1v1 against a hard AI on a map like Centrifuge.  Standard multiplayer settings are to have pirates off and fast/faster speed.  The level you are playing at is lower than the AI that replaces a dropped player in online.

If you'd prefer just to go straight into online then you should consider playing a few team games versus AI, rather than team vs team.  However most of these will also be at a higher difficulty level.  If you do play team vs team you will be a major handicap for your side, a 1v1 game against a sympathetic opponent would be better experience.

The AI is retarded in comparison to human players.  For a better experience, I think your best bet is to continue to play it in single player for a couple more weeks until you can beat the Hard AI without too much effort.  Also, you want to become familiar with and feel comfortable with all three races and to be familiar with each race's tech tree.  You also want to have an understanding of each race's strengths and weaknesses relative to one another as well as an understanding how the different types of units stack up against each another.  You should read Raging Amish's unit comparison guide (sticky thread) in the Strategy forum as well as other threads in the Strategy forum for a while.

Once you feel really good about your understanding of the basic game mechanics, the races, the tech trees, and the units, then consider coming online.  Note that you can come online now and play comp stomps with other human players against AI opponents, but I recommend holding off on playing other people for a while.  Also note that your best bet for finding newer players is to play the regular original Sins (vanilla--not Entrenchment or Diplomacy).  With another week or two's worth of experience under your belt you might be ready to start playing against some of the new players.  (I think some of them aren't much more experienced than you are now.)

Agreed i do not know much about diplo seeing as to how i left but once you have a basic comprehension of the game than go online and find noob frendly players (greyfox is a good bet there if he is still around).

Whilst getting familiar with Sins on single player is not a bad way to start, you will learn quickest by watching replays and actually playing online.

I tried to find some - do you know where to get some compatible with the newest version?

If anyone is here that is in a comparable situation feel free to write me, we maybe could start a newbie group and start on a bit lower level than the rest ^^

Online gameplay is an entirely different kind of animal.  I can handle Single Player games no problem, but Online Players have lots of strategies, as well as ways of taking advantage of units, using them in ways they weren't meant to be.

Build lots of LRF, Light Carriers, Flak, and a few Light Frigates as your core fleet, Carrier Capitol Ships are the most powerful right now, but usually a Colony Capitol ship should be your first for quick expansion.

Everyone here is correct that you should have some experience with the hard AI under your belt before you go online.  A lot of people go online because they no longer feel challenged by the unfair AI, so if you haven't even tasted the hard difficulty AI you're unlikely to find other players of similar skill level. 

Now, on the other front you need to have some understanding of every faction.  You should be able to identify most (if not all) of the units at a glance and know their special abilities, or at least the gist.  If you're already learning all kinds of other things, it's just too much to worry about if someone pulls out a capital ship or cruiser you've never seen before and uses a special ability that you don't understand.

If you are willing to learn and listen you can skip SP all together. If you are "I WILL START EVERY MATCH BY SPAMMING TURRETS AROUND HW EVERY FREAKING TIME AND NO ONE WILL STOP ME !!!!1111" type of a player then stick with SP. Sins players bashing every new guy is a myth, only morons have a hard time. If you are willing to learn someone will usually help you.

The problem is that even if a player knows all of the basics, and the counters. Only a few styles of play is accepted by people online. So the best is to go online and get destroyed a few times and start copying peoples moves.

Yes, replays are the key to accelerating your learning curve.  Not only will you see flawed tactics succumb to superior micro-mgmt skillz, you can dissect build orders and upgrade ramps.  Also, if you watch a replay with a good eco player, notice their progression of research trees, and corresponding transition to military later in game.

Not too sure about where many of the diplo replays are posted. If you go online and play a game, a replay of the match is saved in the single player files.

Whilst many people go online for competition etc., don't forget that the purpose of the game is to have fun at the same time. If you want to learn some basics I am happy to play a few games with you if want.
