Surely you haven't forgotten the huge debate that came up when members couldn't upload at all because if all of them did we'd use up our alloted space (16mb for free) too quickly.
If I'm going to remove the restriction, some of the older stuff will have to go. I think we've used somewhere around 70% of our space and I really don't think we need to use an external image host.
edit: We're at 75% full and most of that comes from all of the attachments. We have about 4.5 mb left in reserve so we don't need to immediately delete anything, but if some members go nuts with no restrictions, then they will go back on.
edit 2: Regular forum members can upload in the following sections: Any of the LBT sections, The Fridge, Silver Screen, Party Room (but not the subforums), After Midnight.
