Sharing your extension on this forum, is it allowed? (Not necessarily part of adobe marketplace)

Hello,

Is it allowed to share link to:

You extenion even if it is not part of the Adobe Marketplace?

Something like a local useful script that can help users accelerate some work or complement the capabilites of adobe software.

(a very basic example: some script that modify you SRT file, so later on you can enhance your PPRO experience thanks to an external tool that helped the user modify their srt file prior to importing it to PPRO, in that case and similar cases is it okay advertise such tool here?)

2) Even if such tool is paid, and not necessarily available for free?

Thanks.
