Can't see the value in this name, so I need to say it's worth reg fee..
Unless you know of any hostels etc targetted towards the extreme sports lot.. perhaps New Zealand hostels.. plenty travellers to New Zealand for the extreme sports.
Check out the google results for "new zealand extreme sports"
New Zealand is said to be the world capital of extreme sports, and the travellers most likely stay in hostels to keep costs down, so maybe try to develop a directory of New Zealand hostels...
