Connect does not and will not use Discord users. None of the commands take Discord user mentions, Discord user IDs, or Discord usernames. All of the commands use Connect's own usernames. If you attempt to view a user's post or account with a Discord user as an argument, you will be met with an error. While viewing user accounts, posts, or something else, you must use the user's name. Not their display name. The only place this is acceptable is the view command, where you mention a user to check their account status.
