I have registerd a few domains recently
on the .mobi domain

basically this is the new market and I want to keep a certain market
for all my mobile domains to link to one main mobi address.

eg I have singles.mobi
dating.mobi
life.mobi

Is there any way this may be illegal ?
I cant see how because so many web sites already use this in their domain names.
I dont want to have problems in the future when some mediocre singles dating agency comes knocking wanting this address.
