On the map, you should be able to drop a pin at a location and search for conventions in a radius around you (i.e. Select Memphis, TN and have a circle of 50 miles around to see conventions)

I think there should a place for Agents and their website to be found so that Conventions looking for a place to find actors, where actors don't want their information public.

As an anime con, It would be awesome to be able to search other cons near me to see what bands have performed.

I sometimes forget what cons I've booked a hotel for or have already booked flights to get to or if I've pre-registered or not. It would be nice to be able to track this. ...and while I do so, keep confirmation numbers in one place so if there's a problem checking in, I can just look up the confirmation number on the site!

I'd like to see a section, accessible only to convention heads using the official convention Email address, where con heads can detail their experiences with Guests. This would allow us to determine whether or not a particular Guest may suitable, or if we should avoid them for being a drama queen.

I'd like to see year-over-year data for cons you have information on (attendance figures, price, dates, guests) represented in some sort of graphical form. The most obvious use is for modeling con growth over time, comparing growth rates, dips, etc. and modeling the data on multiple cons based on geographic location and time. I think this functionality would provide an interesting look into the evolution of cons in different areas of the country / around the world and possibly show how dates and competition effect growth rates.

Make a page with images of various sizes that we can add to our convention web sites or blogs to link to AnimeCons.com.

I know a few other sites do this, but it would be nice to have a place to upload them that doesn't charge for it and has a full list of cons
