With the information provided, I cannot reasonably answer your question. Instead, I'll put the following these three questions to you:Currently I'm using usboard.org (just an example) for 10 years now.
DOT com isn't an option as it's for sale as premium domain for $65k.
To make it shorter and easy to remember.
- Why do you wish to change domain name?
Just my own.
- Is your website an 'organization' of some kind, or is it more commercial in nature?
I would like to retain my primary name/keyword.
- If you are already considering a domain change, why not consider a completely new domain rather than just a change to the TLD?
