Waht's the easiest way to offer users a way to book places on a one-off teaching day? How do I do this in CBsubs? I want to offer a deposit option and an upgrade to full payment. This is a music teaching event and I want to offer instrument hire also, booked against a limited number of instruments available...

thanks krileon; I admit that I very soon realised that I could do it using one-off plans for deposit and full pasyment; I also want to be able to collect other information from registrants, but I guess I can do that by adding fields to CB and showing them at registration; This is a no-more-than twice a year event so I dont need a full-blown event memnagement extension;

Well, having tried the option of creating a special plan I have two problems; if I choose a Merchandise type plan, I cannot choose to display the fields I've created for details about registrants instruments etc; however, if I choose a subscription plan, however I configure it, users who already have subscriptions (most of the likely bookings) can only see the plan if I choose 'allow upgrade'; then, of course, they get a message saying how much more it will cost if they upgrade, which is not what I what I want at all, so I'm still left pondering this ...
clearly, it's a merchandsie plan that I need; is there a way I can collect the extra information I want, by displaying the new fields, or by some other means?

By setting the merchandise plan to be non-exclusive, [and redefining some of the language file entries; eg to remove references to 'upgrades' I replaced 'upgrade possibilities' with 'options'] I now have a working model, except that if a user is already logged-in the fields I have defined do not display; is there a configuration setting somewhere that I have missed?
