Removing a user from a workspace is easy enough, but how do you remove them from the assignee list? I've got a bunch of clients and ex-employees that would be nice not to have to scroll through.
Here's a screenshot of the assignee list: http://spig.io/image/3n2Q0G1x3y3d
If they're still in the assignee autocomplete, odds are they somehow haven't been removed from the workspace entirely. They may still be guests of the workspace or something. Best to get in touch with support and include your workspace ID so they can find out what relation the users in question have with your workspace and why they're still showing up.
