Yeah, I thought that there was an RPing reason behind the desire for my URL, and I do feel sorry for them, but the word 'Dolorosa' was around and being meaningful long before Homestruck and they need to just deal with it. You'd have to be pretty unimaginative not to be able to modify the word in some way (I've seen people add in extra vowels or underscores when their usernames of choice were taken), or not to be able to find some kind of reference to the character or source material that would work - like you've done for Giles (which, I should add, is an awesome choice).

I think it's healthy to have an online identity you can, well, identify with. It helps everything you do online to mean something, and means that you actually leave a mark on things people might remember.

I couldn't have put it better myself.

Deliberate icon choice (of character who struggles deeply with the name she's been given, and with a quote that is all about the slipperiness of names and identities and is Extremely Significant) is deliberate.
