Events+ Custom Fields

I need to be able to let my users register for an event using a form. I do not want to force them to login or register for my wordpress blog/facebook/twitter.

How do I do this as it’s a pretty basic functionality?

Moreover I read(and this is why I donwloaded your plugin) that events+ supports variable amounts. That is it supports events for fundraisers that may or may not be free alowing users to say how much they will donate.
