It helps to have at least a name to associate with a post and some mailers strip off the header, so the receiver cannot reply unless there is some kind of internal address. The major language of the list is English. Posts in French or Khmer are also acceptable. Sometimes there are mail delays of 24 hours or more. If you do not follow the rules above, you may be sent a warning or banned from the list depending on the severity of the infraction.
Profanity is cause for instant banning.
The list server is actually a program. You send email commands to the machine, rather than a person. In the following, the command is written in upper case and any parameters are in lower case. When you send the command, the case is not important. It is focussed on a region, rather than a technical or specific discipline, so there is a tremendous range of interests represented.
