Q: Is Mebeam free to use?
A: Yes, the current Mebeam is free and there will always be a free Mebeam version.
However, there are plans for a commercial / business version with specific options.

Prerequisities:

- You need Skype v3.6, v3.8 or v4.1 or higher to be able to use it.
Other versions may not have the 'Send Contacts...' menu item.
- You have to add the Mebeam.Video as a Skype contact, once.
If the Mebeam.Video Skype contact is online, you can use it.


How to invite contacts:

1. Click with the right mousebutton on the Mebeam.Video contact
in Skype and select the 'Send Contacts...' menu item.
2. In the new window, your contactlist will show and you can add
contacts (also multiple) and after adding, click the 'Send' button.
3. Mebeam will generate an unique room and send the invitation.
4. You and your selected contacts have to click on the invitation url
in the sent message(s) to meet eachother in that Mebeam room.
