NOTE: If you have participants who have previously entered t-shirt sizes before you remove the option, the T-Shirt Size field under the Edit Registration Information tab in Bookkeeping > Manage Initiative records will read "No Shirt Available." This does not mean that your previous data is lost. You can view any previously entered t-shirt sizes by reporting on t-shirt size through a People: All Participants Report.
