I had issues trying to add my vendor links this evening until about 8:45 PM EST... Then I noticed a new message: "We have migrated your community and all of its content onto new wiki software."
It looks nice! No humongous changes--everything just looks freshened up and clean. I was able to add my vendor links.
The only challenge thus far is my attempt to create a new page. I'm fairly tech-literate, but it seems as though there's no template to use to create a new page.
