I know a few people over at GT are looking for new forum software as the existing forum hasn't been developed for a few years now so I was wondering if there was a Gossamer Threads importer available or of there were any plans to create one. I know that GT have a UBB to GThreads importer.

It's not in the list on the downloads page.
