subscribe
and nothing else.
If you prefer digest mode, send the subscribe command to PURGET-D-request@rootsweb.com.
To post to both PURGET-L and PURGET-D, messages should be sent to PURGET-L@rootsweb.com. Messages sent to this address will appear both places.
To unsubscribe, send the command "unsubscribe" to
PURGET-L-request@rootsweb.com (if in mail mode) or
PURGET-D-request@rootsweb.com (if in digest mode.)
To switch from one mode to the other, unsubscribe from one and then subscribe to the other.
There is no "no mail" mode - if you want messages to stop (e.g., when on vacation), simply unsubscribe.
