4 Player Chess

I have been playing on this site on and off for a little over a year now. This is actually my first time using the forums though so if I am posting in the wrong section, I apologize.

Okay so the topic at hand, I find 1v1 chess stressful and almost always play puzzles or against the computer due to the stress of playing an actual human and losing. But I do love the game (weird relationship but I am sure many can relate). Anyhow, I would like to play some 4 player chess games because I feel those are much less stressful due to the feel that they are more 'for fun'. However, it always seems that  the 4 player chess games are almost always high level players (compared to me which is quite low). I feel it would be discourteous to jump in such a game being such a newb. Any suggestions on how to handle this?
