I need a wordpress plugin, where I can create accounts for promoters and they can submit their events and I have just to confirm them, they can still edit them. The events are automatic listed in order of the date. I want also that the event if I approve it, automatic be listed on Facebook as a event. And on the website is a buy link, where people can buy tickets and by eight payment, they get automatic a downladable ticket. Actually right now, I get a mail of a promoter and I have to do all the steps manual.
