If you know the title of the threads, you can search for them. You can also try searching by content...but other than that, there's not much you can do about it.
The links didn't technically break, the addresses just CHANGED. Like was suggested, try out the new search feature, it's MUCH nicer than the old one!
I had hoped I could edit the links to add/remove something and have them point back to the same threads. It's really going to suck to search them out and replace them that way. I have probably 50+ links saved.
I just noticed that since the big forum change, all of my bookmarks/favorites links are broken. Is there an easy way to repair them, or am I SOL?
