I dunno, as a sysadmin who works almost completely with open source software, I myself am often in the position of "I just want to ask one question"... it definitely gets to be a pain to go through signing up for a list, (maybe) waiting on moderator approval to join, finally being able to ask my one question, get a response, and then unsubscribe, all the while, receiving all this other list traffic not germane to my one question that I really don't care about (and as we all do, I get too much e-mail as it is)... there is some real utility to being able to shoot a question to a list & just ask for response to personal e-mail, or read in the list archives on the Web and not have to actually subscribe to the thing. If the system permits posting from non-members I'd vote to keep it that way; I don't feel like the list is excessively spammy... so long as the mods don't feel like they're putting excessive amounts of work into it?
