Bug - I have added and deleted users several times. I have hit an issue whereby I can still see users in Fluent Communities, but they are no longer visible in wordpress. Again, these bugs are to be expected, as they are stamped out, the product gets more robust and better. Thanks again - Fluent Devs
Note...I deleted the users through the WordPress admin pages not through Fluent Communities. This may be a key in that the delete does not leverage a trigger or have a key field that caused records to delete in the fluent data. just a thought
