Hi, I might be wrong here, but I suspect the above mentioned tag was automatically added by the "old and obsolete" mailing list, someone with actual knowledge of the old mailing list might want to add a more correct/proven answer.
I can say for sure I never bothered adding any tag during the previous 3 NC projects I've taken part in. Not a big deal thou will try to remember the tags from now on.

Hi, I suggest to start the subject of the mails sent to the NetCat mailing list with the tag [90cat] as we did for the previous NetCat editions. In this way who want can set up a specific mail filter and keep the mailbox more organized. Thanks, -- Giuseppe
