It's always nice beaches somewhere, as well as people wanting to do some nudism there. Thus, nudes-beaches.com is the right place for them, no ? Any evaluation ? ...
I agree with urlguru. It's definitely nudebeaches and nothing else.
Now if you wanted to showcase nude photos (nudes) and lovely beach sunsets, you could conceivably create a site combining nudes-beaches but you must know you are pushing it. Not a nudist site, imo.
