Instead, pick a 2 or 3 word phrase that describes your project, and use that.
Another tip: Don't do a "domain availability check" until you're ready to buy the domain. I did that once and someone else, seeing I did the request, grabbed the domain. It turns out that the list of "domain availability checks" are sold to squatters.
Also, pick your proposed domain name and Google it. Look at the first couple of results. If they're all low PageRank, go ahead and take the domain. Most people use Google now instead of typing the domain into their browser, so you want to be #1 in Google for your domain name.
