I am in the 14-day trial period for Premium and would like to continue with it, but I do not need to have multiple members. I am using it for my own organizing and would like to use the "guest member" functionality for the purposes of using the calendar so that I can separate out my different projects and clients and benefit from all of the multi-board calendar features. (Both the table and calendar views rely heavily on the "members" for filtering/viewing/sorting, and I would like to use that field but cannot without having other members. I will not be overlapping boards - so could use "guest members" and not pay for the additional users, but I do not have real email addresses for them. Said differently, is there any way to create "phantom profiles" without creating unnecessary additional email addresses? And, if I do that, will that work? Thank you for any additional information as I will be making my upgrade decision within the next 10 days.
