Is it a joke? Where have you seen that registered users must fill captchas, and this also after 36 written topics? You mean, users in k2 community are spamer and you must protect your forum from them ? your art to deal with your community isn't satisfying at all: i mention only a duplicated urls issue, which wasn't answered till year, and it is not only my opinion. But to force active users fill captcha and waste own time with it only to help other user, what is actually primarly your task, is not acceptable.
