So these forums are based on a many-year-old version of MVCForum. And while it mostly works pretty well there are some annoying bugs in it and things that don't work as well as they should.
Unfortunately I can't perform a straight upgrade of the forums, the databases are too different for a migration to work. So it'd be an all-or-nothing approach.
This would sadly mean that everyone would have to re-register. The plan would be to keep the old forums around on a different subdomain so users could continue to access them for a while until everything was sorted.
However it would mean a slightly better design, better spam filtering and better search.
So what do you guys think?
