Longer reply here, but I'm sort of going to be really busy with school for a little while so yeah, haha. I do try to post around as much as I can, even though I've been lagging with that ever since college started, whoops. But yeah, I have to agree that the first impression does a lot! I personally got welcomed very warmly, and I'm lucky I did because I probably wouldn't be where I am if that wasn't the case.
Oh and I hope your test goes well! I mentioned that I was gonna be busy, and that's exactly why. Exams need focus and lots of preparation, after all. :p
