Questions about the Profile FAQ module (and a comment regarding 'forms')
Using Jamroom
It is not as easy as just renaming the module, there are functions that have to be named a certain way in order for modules to work. You'll want to check out the Module Development docs here:
https://www.jamroom.net/the-jamroom-network/documentation/development
That being said, you could use the jrFAQ module as a guide to create a module to suite your needs.
Or, there is also the Aparna module, which allows you to create custom modules and then add any new/extra fields via the form designer, which will also allow you to show certain fields to certain quotas.
Aparna Module Docs:
https://www.jamroom.net/the-jamroom-network/documentation/modules/853/aparna
And you can download the module via your ACP > Core > Marketplace
Hope this helps!
