Guild Operation Runs

We have a number of new members so I thought I would pose a couple of questions to them (and for older members). Currently, the guild runs story mode ops on Saturday nights and hard mode ops on Sunday afternoons. We alternate between empire and pub sides on Saturday nights and typically run pub side on Sundays. Both days we run 8 man, not out of choice but because that’s as many OTG members we can get. Is there interest among the members to expand those groups to 16 man ops? In addition, do OTG members want to add nights to do additional ops?
