There are a lot of solutions that work…but few that integrate directly into this site easily.
It’s a trade off. This is an open source .net forum (standalone even) integrated into an open source cms; so yes there are bugs…
I have multiple stacks worth of various variants of popular things, but there is also the question of the time to migrate everything to a new platform, particularly ones I don’t know well.
For example, much of them are php; I haven’t used php since the late nineties, and have never been a fan of it. And to be honest, I haven’t done a heck of a lot of *nix development and minimal systems since the advent of Windows NT. Prior to that I was all *nix and VMS. But I started working in MS based business environments; smaller shops that preferred windows to *nix.
Anyway a hosted solution is unlikely to integrate well. And trying to keep themes and look/feel consistent across platforms is a ton of work.
And it’s not just this site, I have multiple sites all of which would have to be migrated otherwise I am maintaining too many platforms.
