Most of the staff have scene axx on the top trackers, and quite a few in the IRC channels have usenet access also. If you're after something in particular just pop into their IRC and get chatting. It's not too uncommon for people to grab something from usenet quickly and pop it up on the tracker if you ask nicely, also most have request sections these days if there's noone helpful around in the IRC.
It's taken me a few years to get on the sites I wanted, but I'm quite comfy where I am now, with a backup for each and a few 0day's thrown in for good measure. Plus there's always warez sites for those really obscure things! lol
