All the old blogs and threads can now be found in the new forum.
Good thing I converted the phpBB forum and all the data to use the SMF software before I moved hosting. For some reasons the phpBB forum didn’t want to be recovered 🙁 But SMF is better in many ways (which is why I switched). Originally I planned to migrate all data to WordPress, but the SQL tables behind the two softwares are very different, so it looks like it’ll be a lot of work that I’d rather not do at this point.
