would my clients need to register an account or could they give feedback as a guest too?

Hi smatsumoto! Glad our call was able to sort out how to share without having your collaborators create an account. Thanks again for your 5 taco review!
For anyone that has the same question, simply activate the link to share that will allow any guest to comment without creating an account. Hope that helps!

I read this and buy a plan with 3 codes and share my first project with a client - setting their permissions to "can edit" and sharing to their email. They tell me the share link takes them to a Notetracks registration page to sign up for a 7-day trial period to Notetracks but doesn't seem to indicate that doing so will give them access to the project or be of any use beyond 7-days. There doesn't seem to be any way around it and It freaked them out.

It would appear that people have to create their own Notetracks Pro account to even view a project I am trying to share with them but it isn't clear to them that is even the case. Is this how it is supposed to work? Is that how it's designed to be when you share links to projects?

Are you going to add them to your mailing list or spam them to upgrade or something if I tell them they have to register with you to see the projects I make available on Notetracks?
