The Contact fields accessed under Configuration apply to all events with only the ability to differentiate between paid, free and group registrations. To avoid us using custom fields, we would like these contact fields to be set per event, rather than per installation. For example, for some paid events you want to collect full address information, for others just an email address.
... and to tack onto this idea I'd like to request the ability for DT Register to turn on/off the pulling of information from the current user's profile on the site to pre-populate some fields so there's less typing.
I run two events per week and about a dozen of them register for both. Nothing is saved, data entry-wise, so they have to type in their names, cities, etc. each time. It'd be great if we could pull that info from their site profile or even have a cookie/temp file that's good for 10 minutes so that if they do another JEvents/DT Register item in that time, fields are pre-populated.
