Sorry if this is not what you expected in this list but i can't subscribe to the PF mailing list, i send an email to "pf-requ...@benzedrine.cx" with body subscribe and gmail send me this:
"Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 gmail (state 18)." I know that this mailing list is not for this, thank you.
