I’m updating bbpress.rb to have it deal with attachments (now it inserts a link to the attachment on the original site) and create permalinks for the old URLs. The old format is `/forums/topic/slug’. For anyone who knows how to write an Nginx redirect, it’s pretty simple to redirect that to /t/slug…

Thanks, @falco . I’ll take that as a “no.” There’s no reason not to have the importer add a redirect for every topic, and no reason to make it easy to turn off that functionality (e.g., by setting an environment variable).
