[Staffslug] Listing who's going to the meeting

Hello all, Firstly I have an apology to make, I remember someone posted a message about how we say "Can attend" etc to the meetings via a web site instead of having emails bouncing around on the mailing list, but I've forgotten who it was and the link to the site. So, if the very kind person could re-send the link so I can have a look at the site to see if it will work for us, I would be very grateful? Dave
