Tom would have to do it. Go post something in the Suggestions forum. The only problem, and no offense to our userbase here, is the fact that even if we put a notice or mandate something needs to be done a certain way, there's always going to be a good percentage of users who still post the same stuff in the same places w/o giving a thought to the idea that perhaps there is a standard way of doing things.
...that and the fact that whatever solution is in place will likely be trashed within two weeks by various users who figure that a sub-forum entitled 'Themes Requests Forum' is the best place to ask how to get their AIM buddy list to show up on their recently downloaded Google Talk client (seriously, some people just never cease to amaze me) - bet on that...
