http://forums.b2evolution.net/viewtopic.php?t=10641 helps? The issue here is that you are using blog #1 as your primary blog, and blog #1 is an aggregator blog. That was covered in the long description on blog #1 when you first installed b2evolution, but most people don't read that stuff. Anyway the linked page will show you how to hide posts by category from that blog.

Thanks, EdB! Sorry I didn't read those messages carefully. I'll try harder next time.

No worries! Most people don't read them, so every now and then I remember to say here that lots of stuff is covered in the default installation. Maybe someone will see this post before they delete the info from their blog is why.

Hopefully the solution works for you. There is no reason it shouldn't, but I personally have never tested it because I don't mind having linkblog posts show up in my blog #1.
