Is there a community for users of TK-5, the IBM 370 emulator

TK5 is an IBM 370 / MVS emulator that comes ready to go from here: https://www.prince-webdesign.nl/tk5 - have a mainframe in your desktop?

Anyway I would like to find people who can help a complete mainframe noob with probably easy stuff.

I looked in the communities link at the top of the page.

Thanks
