Ask HN: Mainframe developer resources/communities recommendations

Hello all,

My name is Dylan Lee, and I am a Ph.D. student at the University of Tennessee.

I am working on a research project focused on building a greater understanding of the technical barriers faced by mainframe developers when developing in COBOL.

In an attempt to complete an exhaustive web search and ensure we are fully covering all of the COBOL-based forums and community hubs, we thought who better to ask than the developers themselves. With all that said...

What are the different sites/forums/chat-rooms that you use to ask questions and find answers when developing COBOL?

What are some existing resources for COBOL’s common bugs and technical barriers?

Any help will be greatly appreciated! Thank you!
