As in most mailing lists, there are a few rules to ensure the viability of the list for the future. Some topics are appropriate to this list, others are not. Our lists may have subscribers from other LUGs around the state, country, and world. We realize you want to see what Linux users in different parts of the state, country, or world are talking about, but remember that means some topics will be not be of general interest. Similarly, if you cannot take responsibility for your machine and learning what you have to know to admin your system, there's a limit to how long we'll allow you to waste our time.
Plain text is always appropriate and works best the mix of graphical browsers and mail user agants.
One-line replies of agreement are wasteful. But feel free to respond if you have more to say than simple agreement. Remove quoted material from messages you reply to, except for relevant parts necessary to establish context for your reply. Therefore, they're not spam - if you're not interested, just delete that message, someone else on the list probably may appreciate the info. Some disagreements are inevitable but take flames off-line from the list, particularly when it comes to opinions about which is the best text editor, or the best way to certain tasks.
