Can anyone point me to a site where i can learn about domain names?
I don't know how to tell the difference between things like singular/plural etc..

For example what would be the difference between tv and tvs in regards to what people search for ?

Also if I have a 3 word domain such as flatscreentvs.co.uk is that what people have to actually search for? would i appear if they use spaces? i.e. flat screen tvs or do thaey have to type exactly with no spaces?

and what about words around the other way ie. lcdtvs and tvslcd

sorry for all the questions but i am new to this and need to start at the beginning as to what to register.
if someone could point me to a site which explains that would be good. i couldnt find any that good.

thank you
