Hi,

I have an event (http://europarl.me ) and I made a mistake at the start and some of the participants where put in a group, but not registered as participant to the event. I fixed my webform later on so they are properly registered

I tried to correct it by selecting all the contacts in that group and adding them to the event. It's creating an even bigger mess because now some participants are registered twice.

Is there already an easy trick to correct that, or is the best to order the participants by name and manually remove the duplicates?
