I have created a small site using google-sites, and I listed a handful of people as collaborators. Some of them have gmail accounts, while some don't. I would understand it if only the users with gmail accounts were able to edit, but that is not the case. Some users can, and some can't. but some gmail users can, and some gmail users cannot.
Should I be focusing on the user, the browser they are using, or is there somewhere else I should look to troubleshoot this?
Does it sound like user error? I have asked them if they see the EDIT button at the top right, and they say no edit buttons of any kind appear.
EDIT: In researching this, it appears that sometimes it is related to the difference between google apps accounts and gmail accounts. Can anyone add anything to that possibility?
