Can we make mailing lists for PM? e.g. PMgroup=name1,name2...name(n)
What are labels for? I made one but they look like they group existing mail.
It doesn't look like there is a feature that allows members to create mailing lists within the private message system.
It looks like labels are a way to tag or categorize personal messages. Once you tag messages you can click on a label name to see the messages that have been tagged with that particular label. I have a couple hundred messages and never noticed that feature. I'm not sure if it is all that useful.
