I've been lurking quietly on this duscussion but I just had one thing I wanted to say.
I left my last host (who are also located in Michigan, I will let you guess who they are!) because my Movable Type installation crashed their server during an attack by comment spammers, and they told me (in an astoundingly rude manner) that under no circumstances would I ever be allowed to run any version of MT on my account with them in future. If they had handled the problem in a more professional manner, they would not have lost my account. As it is, I tell everyone who will listen about my bad experience with them and my wonderful experience so far with TCH.
I was somewhat alarmed at the idea that TCH was going the same direction as my old hosts after reading the mass e-mail this morning, but after coming here to read this thread I am so impressed by, and grateful for, the high level of professionalism that I am seeing displayed by TCH staff members. You guys (and girls) are the best- don't let the few who are freaking out and complaining get you down.
