Any user list plugin for match-making functionality?

Hi, I’ve started using a standard WP installation for my site dedicated to wargames. I’d like to add some “match-making” functionality to the site and I wonder if there’s a plugin which could help me out.

Here’s (ideally) what I’d like to do:

• have each user provide additional data when registering, such as games owned, games the user is looking opponents for, language(s), etc. This data should be editable at any time, obviously.
• make it possible for any registered user to list all registered users and their corresponding data and sort this list according to various criteria (ex. list only players looking for opponents for game A and speaking language X)
• make it possible for any registered user to select one or more users to send them an email
• have this functionality available in several languages

Any help would be greatly appreciated, thanks!
