If I copy the files over from the old forum, those should work just fine. The thing is, we were out of attachment space at the old forum, so I wasn't even going to bother. Attachments were added to be a temporary place to upload something when you didn't have anywhere else to store your stuff. No one ever bothered removing their attachments once they were done with them, though, with one or two exceptions. I had planned on going through and making a list of every attachment, so that the uploaders could go through them, and unneeded ones could be removed, but there's no easy way to do that. So, rather than just upload everything again and run into the same issue, I can upload specific files by request. It accomplishes the same thing, the only difference is that there will still be links to nonexistent attachments in the older posts. It's not the best solution, but it's better than being completely out of space, like we were before. I've uploaded those two files for you.
We have more themes!
