I was thinking this morning that there used to be a french league where you had a map of France and you could see in which city is everyone in France.
I think it could be cool to be able to have a world map and to know in what city we all live. It could help to arrange meeting and stuff like that.
**Imagine you want to do a clan meeting could be cool to quickly know where exactly the most member live**
Or some other stats as the city where the most people play worms or the best skilled city overall...
I might be stat addict but I think that adding an user information non mandatory in the profile is not a very big deal and then you can display it on a map easily.
