Victory! They didn't move on the base salary but offered a signing bonus so I took it. It was more than I would have gotten without asking, right? Also, I got a fabulous welcome/introduction email from the team leader, copying the team, and just about everyone on the cc sent me a "hi!" or a "welcome aboard!" or some nice little message. It was really great.
Thank you, everyone who cheered for me last night when I was feeling fidgety. I'm feeling pretty good now, and waiting for my mom to call me back so I can tell her the good news. :D
