Here is the info:
If you are invited to join the Film Gallery, you will in turn be given an invitation to extend to another artist to join the gallery as well. You can only send out an invite to someone who already has a deviantART account. In order to send out an invite visit the following the page and enter their username in the box and click "invite". You can revist this link at any time to see if they have accepted the invitation. The person you invited will receive a note in their message centre which will contain a link to where they can accept their invitation.
[link]I'm also an animator obviously and I would like to use DA as a close showreel. The staff haven't replied at all in return with my application form, so I assume that either it hasn't gone through properly or they have just declined it... no idea :/ . If you are willing to share an invitation then you would be doing me a big favor! but not pressure at all, you know xD it's up to you. Thanks anyway
