I'm looking at building a form that would cover multiple spaces in our account and give non-users the ability to submit tasks with a basic set of information that doesn't make sense to enforce as custom fields across all spaces. It would be helpful if there was a way to programmatically manage Guests via the API so when someone submits a task, we can automatically add them to the appropriate space and allow them to participate in discussions regarding their suggestions. Ideally we'd be able to check IF a guest account exists, add/remove it from folders/lists, and remove guest access.
