I'm helping a non-profit with some design work. I created printed material for them using Museo through typeKit through my CC subscription. They are using stand-alone license for CS6 InDesign & Photoshop for non-profits; this requires a Creative Cloud subscription and an Adobe ID.
Q: do they have access to TypeKit?
Typekit subscriptions are included with a Creative Cloud subscription. I’m not sure what the deal is for non-Creative Cloud subs. There is a typekit forum. You might want to pop over there and ask. https://forums.adobe.com/community/typekit
There are three weights of Museo that are free, the other two can be purchased.
You would need to export the current job to IDML for them to open it if that is needed.
