The urls to forum posts on the old forum used to be
but now they are
The only difference is the /forum directory has to be removed from the urls. Any urls will then point back to their original threads.
There are tons and tons of links all over the internet, in forum signatures, blog posts, art websites, and all their links to conceptart.org threads are broken.
I'm mentioning this because:
1) for anyone who has an old broken link, you can always fix it just by removing the /forums part, the rest of the url is identical.
2) for anyone clicking a broken link (like in people's signatures here) you can fix it by just removing the /forums part
3) I don't know the actual way to do this, but there must be a way for the web-support guys to set it up so that all links going to /forum go to the right directory instead? Maybe the forums could even be moved to their old directory?
The links are being fixed. That's why the forum slows done every now and then. Hopefully that will also fix any missing attachments as well at the same time.
