Bible study tools in Debian repository - End-user support?

[Richard Owlett <rowlett@cloud85.net>]

I'm running Debian 9.8 and have just installed BibleTime, Xiphos, and 
diatheke. I expect BibleTime will become my primary tool. The available 
documentation has breadth, if not depth.

For the type of usage questions I have, I have found archives of mailing 
lists and USENET groups to be a valuable tool in filling in voids in my 
background to avoid "newbie" confusion. I searched the various homepages 
without finding what I was looking for. One site explicitly stated they 
do not have publicly available user support fora. A web search turned up 
some old posts, all several years old.

Can anyone suggest an active mailing list or USNET group where usage 
questions about these programs would be acceptably on-topic? I find web 
based fora difficult to follow.

TIA
