Ever since I switched to Squarespace version 6, I've been missing the sidebar I used to have. At least, mostly missing it. That sidebar got pretty busy for a while there, and that part, I definitely did not miss.
I've switched to a new V6 template that has a sidebar again, and I'm going to do my best not to let it get as full as the old one did. Please do let me know what you think of the new design; I know there are still some issues left with it, especially the menus. I'll be working to resolve them ASAP.
