Not much at the moment i'm afraid in my humble opinion. Still too early to see which of the new extensions will stick. I have a couple myself so also hope they take off ( i have gym.zone for example in that niche) . As always though, the caviat being its also worth as much as someone is prepared to pay for it. If you contact a few London clubs ,it might fire the right imagination and get you a good few quid. Although at the moment, even with a good wind , i cant see more than a coupe hundred tops to the right person.
