Suggestion:
In the Mindat sub-forums (General, Scrapbook, Rockhounds, etc.), it would be nice to know, without clicking into it, when a thread was first created and by whom.
That way I can tell if it's an old thread that's simply been revived with a new post or if it's a new thread that's just recently been created.
So perhaps a "First Created", "First Post" or "Started By" column that includes the date of the first thread post and who created it could be put next to the "Last Post" column in each Mindat sub-forum.
Many other forums include this kind of information which makes it easier for users to figure out how "fresh" a thread is without having to click on each thread to find out.
