Private event sites that use your URL, your website design style and are 100% under your control, the membership can be set to only those attending the event -
Attendees make good use of private social networking because they can make longer lasting connections before and after the event.
You can create communities in a self-serve manner without any obligation directly from the community on our own website.
The networking community actually on the site is an example of the same instant on, self-serve solution that is offered.
