Hello! I have a proposal that once a thread has a "Problem Solved" label attached, the thread should be automatically closed from further postings. This is really the very first forum I've seen where that's NOT the case. I've created a ton of similar web forums via "phpbb" & "vBulletin" for myself and others whom I've built web sites for in the past. Threads that are deemed done or resolution resolved almost always have automatic closing of the thread.
Continuing the posts should be deemed unnecessary if in fact a satisfactory resolution has been provided. Members can always renew an issue with a new thread if a "different" question needs to be addressed. I've been amazed that I have been ABLE to post things to a thread that has already been deemed "resolved" . . . lol.
