Deleting a user

Yes. Check out this page. 

Here's a brief recap:

When you delete a user:

• All Tasks, Folders, and Projects created by the user, but which were shared with other users, are still accessible by those users.
• Tasks, Folders, and Projects which only the user had access to will be deleted.
• Recurrences created by the user stop (no new tasks are created in the sequence).
• All comments, attachments, and changes made by the user will remain visible, but the user’s profile image is replaced by a generic image wherever it appears.
• If the user was assigned to tasks, you can no longer filter by them as an assignee*. 
• If the user has other Wrike accounts they will still be able to access those accounts and none of their information in those accounts will be affected.

*We recommend reassigning all tasks before deleting a user so that no tasks or projects are forgotten.
