Please follow the netiquette when posting on DotSwarm mailing lists, especially avoid top-posting and thread hijacking (that is, replying to a thread and changing the subject line to something completely unrelated that was not being discussed within the original thread). Apparently some people still have dialup, but we don't discourage posting images around the 1meg mark to show you are using the software to make visual creations!
Configuring your mail client to break lines after 70 or so characters is a plus. If you attach files, avoid compressing small files, uncompressed is preferred. Also please try to avoid posting mails with overly long signatures or nonsense corporate disclaimers that claim the content of your mails is confidential.
