By Emily Massingill For the Times ORANGEVILLE - The Mighty Richland Players Dessert Theater (MRPDT) has planned a community workday at 8:30 a.m. this Saturday, Jan. 18 to bring the public and interested parties together to see what the group is all about and to learn about hopes for the future of the historic theater building on Orangeville's High Street. The entire public is welcome to join the community service organization this weekend, and volunteers are appreciated in any capacity. The open house-type event and workday invites anyone who would like to possibly participate in a show, act as a support staff for productions, help with care or maintenance, make a cash donation or take on any other necessary duties needed to keep the playhouse up and running.
