Hiya. OK I'm a total n00b. I'm having a hard time finding info about basic moves like fwd roll attack, wall spring etc. My machine isn't fast enuff to play the single player

but I seem to be able to jump on a server w/o too much trouble.(I've even been able to win a fight or two

). But I'm never gonna get any better w/o some better moves.
Any input/links etc would be appreciated. TIA.
