This would be a paid project for modifications realted to other posts I've made on this forum:

https://simple-press.com/support-forum/simplepress-version-4-3-0/strange-question-about-blocking-members-vs-guests/

I think the modifications necessary to achieve this are beyond my skillset (which is generally limited to front-end development). Any PHP professionals available to help?  It's needed asap.

Many thanks,

Mike
