Thanks to everyone who signed up

A lot more people signed up than I was anticipating, so the sign ups will be more restricted from now on (you can still sign up, but the confirmation might take a while). I think that there are currently enough people to test out the service (some have already pointed out problems, thanks for these) and I will need to focus on making more functionality for the web site and on the software side. I hope that people who have synthesizers, put them online, at least occasionally, for others to try.
