What I'm not so sure about the BitcoinGirl.Club initiative is that it will succeed. Some members may publish their achievements in that thread, but I'm sure some others will not.
...and I guess OP's idea in theory would be fine but unlikely to eliminate individual bragging threads I think.
LOL.
It didn't take long for a thread to appear.
The senior member gang.Facepalm.
I was also thinking before reading suchmoon's post that the only thing to do if these threads appear is to report them to see if moderation wants to move them but I also thought it would be unlikely.
I don't think we should get too pessimistic about this though. BitcoinGirl.Club's initiative and will concentrate in the thread at least part of those that would have been in individual threads if she had not created her thread, just as has happened with LoyceV's thread on plagiarism.
