I've been on the fence for awhile now, considering the switch to Xenforo. The main thing holding me back is the lack of an officially supported importer for vB4. Is there a reason one doesn't exist? I don't even need it to import articles and blog posts if that's the issue. Just import all the forum stuff, threads, posts, members, usergroups, PMs, etc. Just wondering if this is in the works or if there are reasons why it will never happen.
