i always pressumed the source of the phrase was due to being "logged" by the software. eg a user is "logging on" because he is literally going on the log. If you review the server logs youd see the user on (or in) the log. the same kind of verbage is used in all similiar scenarios. you check in at a hotel for instance.. Check, sign, log, etc etc are all really just various words that roughly mean the same thing. Log just happens to be whats popular on the web.
