I've found a problem with the "Topic too old" thing. Not a glitch or something like that, I just think it should be changed. For example, you look through old topics and see a post and thinks "Ha, that's going to be my signature". You press the Quote Button to copy the code, and then... "Topic too old". I think it would be like this: the Topic too old message would come only if you're going to post something, aka pressing the Post button, so you can type something, but not post it. Or, when pressing "Reply" button, there would be a red message above the message box, like "No subject was filled in", that would say this:
This topic is too old. You will not be able to post in this topic.
This would be useful. I found a funny post in an old topic, but couldn't get it.
