I am stumped

All of the good domain names have been taken

I am in heavy development of several websites right now. One of which is my own community site

I've been at Thesaurus.com trying to come up with a simple, short domain name with the theme I have in mind

A word, a created-unique word (joining words together), or a phrase representing a unique individual or celebrating one's uniqueness

or

A word, a created-unique word, or phrase representing unique individuals worldwide being brought together under one network

The naming of your business could be one of the most important decisions you will make. A name's originality and legal availability will create a real asset value of its own, as it becomes marketed and gains market acceptance.

The name you choose will become the focal point of all the benefits and features that relate to your business. Customers will be able to find and refer others to it in the future.

Since any names that are suggested here may already be owned by another party, I wanted to go a different route...

I suggest either hiring a name creation firm or get together with your friends and/or family and throw a "name party" & have everyone bounce some ideas around. Compile a listing of names that you like the best. Once you have that list, do as much free research as you can before you delve into comprehensive research.
