I'm trying out the demo now, and I have a few questions: 1) Is it possible to ban people who register but who haven't been approved as members? For example, if someone who I know is a spammer registers, I'd like to ban them by email and not by IP address. Can this be done? 2) Can pictures be posted that are not hosted on a site like flickr or photobucket, similar to the way they're uploaded on Facebook? 3) Can I add new tabs in the navbar? If so, how?
