Couple of things, I reckon it's probably because of the forums upgrade you tell us about, but when I try to update my time in my control panel (I think in the 'website options') I get a 'We are treating this as a hack, the Administrator has been notified' page.

Wicked Fun! >>

Also, I want to link from the picture in my sig is this possible atm?

First off, is anyone else experiencing this problem? I can change the time in my profile just fine, but I'll definitely look into this.

Also, you can create a link from an image. Simply make the image, and then surround it with [ url=http://www.yourlink.com ] and [ /url ], only without the spaces. The spaces are just there in my example to prevent the forum software from rendering the code as a link.
