UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Help needed on mark new posts

Hello,

I want to mark all new posts for a user in Version 7.1.1 in showflat.tpl with a different color. alt-1 and alt-2 won't do the trick. Maybe you can give me any suggestions how to accomplish this. It's for the site http://forum.astronomie.de.

I'm a php developer with a very good knowledge of smarty. So you can talk straight.

Regards,
Thorsten
