Yes there have. Plenty. Just look through the resolved bug reports for Fixed issues and look at their titles, clearly some are proper bugs that have been dealt with.
Anyway, what's this obsession of yours with stats? Firstly your post count, now your bug reports.
How about another arbitrary measure of how someone may be valued on these forums - their like : post ratio? We have some like Shelley, Chris D and Russ (naming just 3) who have like : post ratio of more than 1. What they produce for the community and what they say seems to be valued. Others like Sheldon and xfrocks have a like : post ratio above 0.75.
I'm not planning on reporting anything else for a while just so I don't overload Mike and Kier (despite my reports being relatively minor things). Plus, I'm not finding anything else, but even if I do, I'll wait until the forum's bug reports go down.
Also, this may be hard for you to believe, but I don't care about post count. When I bring it up (like 3,000 posts), it's just because.
