Guests and external collaborators

Bringing in someone from outside — a freelance writer, an agency, a client, a subject-matter expert — without giving them your workspace, and usually without paying for them.

Two ways in, and the difference costs money

Share the documents. They see exactly those documents and nothing else. They do not appear in your workspace. Free.

Add them to a project. They get everything in it: the document list, the site connection, everything destined for that site. This costs a seat, even though they are not a workspace member.

The boundary is project access, not workspace membership — which is the opposite of what most people assume, and the usual cause of a surprise on an invoice.

Which to use

The person	Do this
Writing three articles	Share the three documents
Reviewing one page	Share it, or send a link
A subject expert checking accuracy	Share as commenter
An agency running your whole blog	Project access — a seat, correctly

Setting it up for a freelancer

Create the documents, or import the posts they will work on.
Share each with their email as editor.
They sign up, and land in those documents.

They can write, comment, suggest and share onwards. They cannot see your other content, your site connection, your members, or your billing — and they cannot publish.

For a reviewer

Share as commenter. They can comment and propose tracked changes but cannot change the text directly, which is usually what you want from someone reviewing for accuracy rather than editing.

Ending it

Remove them from the document, or revoke the link. Immediate, including for someone with the document open.

Their comments and suggestions stay, attributed. Removing access does not rewrite the record of who said what.
