You either accept there is a flaw in the ointment or not.
I have no idea what ointment do you mean.
There is no flow.Sign-up disappeared because it is not a regular Sign up menu, but Disclaimer add-on. I have asked our friends to move it a bit on top of other add-ons, and now it works. The same you need to apply with your stuff. A little bug on their side, ok.
When you
are in PM, logically you don't need the link leading to PM, because
you are in already. When
you are in Polls, you don't need the link to Polls, because
you are in already. You don't need this menu anymore. Mini-concept. Got the idea?
Checker is not installed on miniBB demo, but the principle of menu building it uses is the same. I didn't understand what do you mean in your last post.
1996 behavior? Show me another software which does it better way.
If you don't like how menus are build dynamically, make your static version of all menus available in the header.
