Thanks! I'm still working out all of the details. I have a name in mind (not my first choice - a lot of the names/domains I was interested in were taken) but choosing the name is tricky. I want the name to reflect services that I feel confident offering now, and still be relevant for services I plan to offer in the future (once I build up my skills more and have done some pro bono work to build up references).
I'll keep you all posted when I bite the bullet, register the name and buy the domain!
ETA: Apparently when I registered on the forums a few months ago I had put in a tentative name that is now in my sig line - that name is no longer in consideration.
