So I choose "capture the flag" because then there are a few men who don't shoot me at once

You understand; I stink!
I have not been thrown out of a game (yet).
I would like some tips of how to play (the flag I like most) and what to do and don't. I really know almost nothing!!
Last evening; I HAD the flag of the enemy (my personal best :icon31: ) and I ran to homebase........I came there and didn't know what to do with the thing!! :icon23:
I asked and got killed!
Mostly I just run around and shoot some enemy's........sometimes when I get close I try to take their flag..........when I see a mate of mine running with the enemy flag; I try to give him cover.
Is there a server just for nOOb's like me?
Then; the gamespy stuff don't wokrs on my pc and I am using the game itself........it don't give to much choises......
Has anyone got tips or a "manual to play online for me"?
