User ThreadWiki Management:

[stevenryals]

Some of my members do not have the "Manage" button for vw at thread level.
I have searched all over and can't find the option to turn that on.
any direction on this?

In threads, the "Manage" button typically requires that users have edit permissions on the thread node. They must be a moderator or must be able to rename the thread. The thread creator usually has this permission.

Once the "Manage" button has been used once to add a wiki page to the thread, any user with edit permissions of the wiki page can modify its content.

Since wiki pages tend to have more relaxed edit permissions than forum threads, it is easier to edit once it's there. You can think of it like this: (usually) users aren't allowed to edit each other's forum posts, but users are allowed to edit wiki pages. Essentially, the thread author grants this permission to others implicitly by using the "Manage" button.
