Are there any post style forums for KOHA on the internet?

No, Koha (note the capitalization) doesn't have any official forum-style discussion site. The Koha mailing list is the best way to reach others using Koha. You can also try the Koha IRC channel: https://koha-community.org/get-involved/irc. You will usually find developers there rather than librarians, but questions are welcome there. -- Owen -- Web Developer Athens County Public Libraries (740) 737-6006 https://www.myacpl.org
