honestly you wont find this in guild wars (the helpful active friendly) guilds. if you want friends do a random free run ascalon - droks. talk to them while you run and make some friends there. add them to friend list.

as for helpful. what could you need help with on guild wars? everything in the entire game is pugable.

and as for active, do as lenny suggested. make your own guild. and set the 1 rule as no inactivity past x weeks. after that kick them, and reinvite more people. when you make a guild it takes time. you have to invite a HUGE wave to get started. then filter through and kick the ones that dont belong. then invite another HUGE wave. and again filter through everything that is left. after that you can pretty much just invite when and who you see fit. because at this point you would have a nice community.
