I had a similar, specialised page for this kind of thing. It was a simple flat file database to a text file, with a tiny CGI script to allow people to enter their details and run a search on game and locations. From memory, it included name, email address, location and country, each version of Epic and a text box for the specific forces, BFG (+ fleets) and Warmaster (+ armies).
It worked relatively well, but ended up getting huge amounts of porn spam as there was no security on adding details. This meant that I had to monitor it weekly, as well as making alternations, etc. It became difficult to keep going, and I wasnt sure that it was used enough to warrant it.
Then I deleted all the spam porn links, and certain people here complained that now they would have go out and look for it online.
Something like this with a login I think would be good. Even as a very simple system running for a couple of years, we had over 200 genuine players registered on it.
