Hi,

Only problem is while creating a new chatroom, i am getting the error user warning: Unknown column 'tags' in 'where clause' query: SELECT og.gid FROM term_data t INNER JOIN og_galleries og ON t.vid = og.vid WHERE t.tid IN (tags,6,1,2,3,4) in public_html/includes/database.mysql.inc on line 172..
