I just completed another new skin named ticktockpro based on this design by dcarterdesign.
You can see it now on the mojoPortal demo site, and I'll have it in svn trunk later this evening.
That makes 3 new good looking skins this week, and I plan to do more of them in between my other work.
Did you know that you can preview skins with a query string param? So you can see each of the 3 skins I made this week using urls that specify the skin like this:
http://demo.mojoportal.com/?skin=tabular1
http://demo.mojoportal.com/?skin=techmania
http://demo.mojoportal.com/?skin=ticktockpro
