Video in MMS
Allow the user to send video in an MMS message. In mango, only sharing via email is supported.
Great suggestion, but these are consumer features – and not developer platform suggestions. As such, declining this idea to give you back your developer platform votes.
You can submit and vote on consumer features at the Windows Phone Feature Suggestion Box here http://windowsphone.uservoice.com

You can send video/audio attachments in WP8
All phones have this!!!
Sending audio clips would be great too.
