I'm using 2.9-beta-2 (from SVN).
For a while now I am trying to create a category named "C#", but I can't cause WordPress thinks I already have one named like that. Confusing it with my category "C++".
This is highly annoying. I can imagine why this happens and would understand if this won't be fixed so I would gladly settle with a workaround (like inserting the category directly into the database) if I knew I could then blog about both languages :P
Thanks in advance
