Does sound pretty interesting... installing Squirrel is on my list, but down on my list for installing and configuring..

I have not really looked at the (well not for awhile) but I am sure if you want you could set it up where, when you register for the board, it will automatically create an account for you. Then in the User Control Panel, is where you can have a lot of options, like changing your email, checking your email account, etc.. so that they can do it all from one control panel

I have intergrated a few things into mine, so that if they want to check stats or other scripts they can just view one area, and get what all they need. So I am sure this is possible
