I like this app. - it works nicely for me. I often used to forget to manually login to iChat and don't like to have it in my logon items list because of the way iChat starts with the Buddy List open. I have more than enough items in my logon items list anyway! That said, I have two comments for the dev.:
1 The app. would be even better if there was a setting that allowed one to choose what status to logon under. I prefer 'away' and it currently defaults to 'available'.
2 The links on both VersionTracker and MacUpdate sites to the dev. seem to be broken.
iChatOnLogin.app
Logs into iChat during login without starting iChat.app.
