Bug - positing with a colon in the forum

I found another bug in the forum. It seems when you use a colon in the post and trying to save it, and alert apears with error as an entry. 

Test, Test; Test: Test? Test! Test:Test

I'm using Linux 32 bit.

seems to be completely random. It occoured for me several times when posting an url on macos...

Please note that you cannot write a link into the headline. Other than that there are no restrictions, so I don't what exactly is the problem here.

He's not talking about adding an url into the title of the thread Simon. He means in general when adding a link somewhere in your message.

Sometimes posting an url without wrapping it in url bb tags ends up popping up a warning/error dialog box when you try to submit your reply/post/edit.
