I think I've done about as much as needed now to help with administering the Iraqi-History group.
To keep the group going well make sure to look for new members, especially from Iraq, and look for the newest artwork on DeviantArt as older artwork usually is by users who are no longer on DA. Also if you or other administrators leave the group, make sure to find replacements for them to keep the group running well.
Iraqi-History looks like its doing well, and there is artwork and photos from all eras of the history of Iraq.
