I'm still adding blogs. This setup makes it easy. All I have to do is click on the tool icon on the appropriate bit of the sidebar and up pops the add-stuff screen. No wandering through menus.
I've added 'Hibernation Corner' for blogs that have ceased activity but are still there. You never know when one might pop back to life. The LiveJournal blog will go in there too once I'm confident enough to stop duplicating posts.
Adding extra blog lists is easy. I just click 'customise' and a page comes up showing the layout. Click 'add gadget' and the options appear, add another blog list gadget and drag it to where you want it to be in the list.
I really should have moved ages ago. This is the place to be if HTML makes your eyes wilt.
