A couple of thoughts:

If you typo a thread, just send a quick note to a moderator (negative, myself, ennis) and explain what the thread title should be and a link to where the thread can be found. We'll be more than glad to fix it.

Exploits can be found at a variety of places:

http://www.packetstormsecurity.com
http://www.netsys.com
http://www.k-otik.com

I also subscribe to BugTraq and Full Disclosure as methods of finding "exploits" as well as visit as a guest http://www.zone-h.org and poke around the 0-day forum for the occassional "slip". White hats rarely get 0-days unless they run an active honeypot in my experience. You'll have to go somewhat into the edges of the blackhat community to find these things.

Lastly, (and this point is for everyone), we know each other based on the handles we present and how we present ourselves. Many of us are by nature paranoid about the info we give and who we give it out to. We don't know if we are being socially engineer'd by someone if they ask for an exploit, ask for help in solving hack on system at ip x.y.z.a, or maybe they are just an admin trying to do wargames on their play boxes at home to figure something out. Perhaps people should keep this in mind on both sides.
