I think it would be a good idea to have some kind of list guidelines posted somewhere even if they were to say everything goes so that people would be able to make an informed decision as to whether they want to join or not. For me personally, I joined with the idea that this was a list about Speakup specifically and that maybe every once in a while Linux or Linux access questions for the blind might come up from time to time. But honestly, I would not have joined if I knew floods of Mac OS X with other screen reader hand holding would hit my mailbox with no kibosh put on it. Now, I am certainly not telling anyone how I think the list should be run at all. I am just saying that I would have liked to know that ahead of time so I could have made a more informed decision about whether to sign up or not.
