My goal is to make Mixergy into an invitation Web site that helps guests mix. If you give us feedback, I’ll link to you here.

At a recent event, I asked Mike Prasad, who organizes “TweetUps” for his input. Here’s what he said:

Roger Vetruba of movoxo.com says:

hey bud, I really wish [the invitation emails] contained a google-friendly time-date, so that Gmail would automatically ask to add to my calendar!

This is a tough issue.

Hosts want their guests to RSVP. If we include the event details on the initial invitation email, guests will be less likely to go to the invitation and therefore less likely to RSVP.

But I understand that guests need to get an event’s date and location by email. So I’ll try something new. After guests RSVP, I’ll send them an immediate confirmation email that will include the date and time.

Anyone have any other ideas about this issue?
