I'm looking for a service similar to the one at www.fidelitytraining.com from Microsoft's now defunct bCentral for an online class registration system. Free is a very good price, but I'm open to suggestions.

Thanks!

Online class registration can be fairly complex so free is unlikely - but you could do worse than try out http://www.eventhq.co.uk, which with no setup fees and $2 per confirmed booking is good value for the features on offer.
