Well, it's not an issue of "if it pleases me", I'm just pointing out a mistake as a fellow writer. I abhor (well not "abhor" abhor, I simply dislike) inaccuracies in a sign-up that can be, uh, fairly easily remedied if armed with a dictionary and / or search engine, and this was one such inaccuracy, so I responded in such a way.
Apologies if I sounded offensive or anything... you don't necessarily have to change it, I'm just putting that out there. XD
