By this mid-way, I would like to take a moment to appreciate everyone for their time and efforts and there are some really good entries and we are going to have a hard time choosing the best one, thanks to each and everyone of you all for the entries.
Let me answer the questions being asked.
I think people did not read rules and requirements properly and make entries.
Yes, it would be better if they can avoid already used names because we want something unique but appreciate all the efforts and entries by everyone.
OP, do we need to check domain name availability for suggested names?
We will be able to find the domains as long as the names suggested are unique and never used before then we would be good.
