Thanks, and you have a good point about offline access; I'm honestly not sure about how big a gamble this is. The thing is, I've noticed that whilst a lot of people who work in IT are completely against the idea (myself included, to be perfectly honest), it seems that there are also lots of people who plainly - for want of a better term - don't give a damn.

My rough plan is to give it a week, and if I don't get even a couple of sign ins by then, spend the weekend sorting out session fun. If you like, I can reply to your comment with an update? :)
