GM/Co-GM editing each other's posts can be risky if they get into a conflict (which does happen occasionally), but what Mahz has spoken of in the past,
@JBRam2002, is adding a "0th post" to each tab, where GM and co-GMs all have full edit permissions.
Though it could be interesting if posts could have a checkbox thingy available only to GM/Co-GM for making any later post a "GM post" with the same edit permissions as the 0th post. Sort of a system for distinguishing GM announcements.
We made it fairly simple for our RP when it comes to sheets and dealing with dropouts.... any dropouts that never posted in the IC, we ask the mods to hide the sheet post of. But more importantly, anyone who gets their sheet approved is asked to post it in a hider. That way, its easier to scroll to find a specific sheet.
Oh, that reminds us of a useful feature we think we recall from the pre-guildfall guild... ability to disable signature on a post-by-post basis. That could perhaps be very useful for certain CS/IC tabs to make reading even more streamlined.
