Hey Mat, and Welcome!
what version are you using?
"Active topics" shows links to the topics that have new posts since your last visit or in the period that is chosen.
TTBOMN - there is no interface way to disable user profiles, you need to bite the code to do that.
As for the negative post number - I've never seen that. Are you sure you aren't seeing negative points, rather than negative posts?
PS - No need to cross-post!
... But trust me on the sunscreen!
