A: Hi Mat, thanks for submitting your query. Here's a quick clarification between the three:

Admin - They hold the topmost account limit with all permissions. Additionally, admins are present in all the projects (by default) created by any user.

Collaborators/Users - The users are the ones, whom you add to your project with different access levels, like:
View, Comment or Edit access on Web
Comment access on Mobile, or
Agent or Member access in Chat

Guests - They can review your projects without the need of signing up or logging in. All they need to submit is their name for identification purpose while adding comments.

We hope we've clarified your doubt, please feel free to revert in case of any other queries or concerns.
