Actually, as long as his bugs are legit (dupes, hacks, invincibility, ect) sigil wants to hear about it...that is why they have beta testing in the first place...then when the game comes out, we dont have people hacking their toons to max levels with the best gear. The one thing I would do different...when it comes to bug reports, I would just give a brief description and say email me if you need more...after all, they are busy, and if you can just tell them the general area of the game that caused this (or show them how to trigger it) then thats really all they want. Yes, beta testing is fun, and yes, there are people who want in soley to see the game before its unfinished, but this is the wrong mindset if you ask me, I agree with your ideas Cyndre.
EDIT:
I do agree with you Greymain on the idea of the cgm people (for the most part) probably being best to not report things unless they know what there looking for and they know how to send a short simple message to sigil saying what they found....
