Argitoth is an experienced host and his advice on these matters is worth noting. In particular, he's right about people dropping out. There are a huge number of people out there that will cheerfully sign up, play a couple of turns, then walk away from a game without a word, without going to computer control, nothing. The option of force-hosting at a known time is indispensable. The recently-added master password can also help with this.
