Thankz guyz for da suggestions.
* .lk - will not work in my case. i want to represent my company as an international graphic design company on the internet. so a .lk domain will not come in google.com at a top potion for international searches imo, unless if the user uses google.lk for searches.
* .biz - ofcase a considerable one.
* .org - Nop. my company is not an ngo type.
* .net - yes ofcase the second choice after .com.
* .co - i read about .co yesterday. it says .co has released by godaddy as an alternative to .com. com and co sounds almost pretty similar. further co mean company.
so my concerns now is weather .biz .net or .co.

let me wait for few more feedbaks. i hope to reg the name morning.
Thanks folks.
