Really, the only thing that needs to happen with regards to the Morninglord temple is people need to treat it as an actual place of worship versus an inn that vampires have trouble entering and a place of free healing.
Player-run efforts to hold sermons and actually do things in the Sanctuary of the Coming Down never work, and I feel for the players of the Morninglord faction in trying to enforce the setting in that place, I really do. I've noticed this long ago when Geiger was leading the ML faction as William Graham. If you try to start up singing of a religious nature in the temple, you will be threatened on a regular basis with no regard given to the NPCs that are there, and much more. The absolute WORST instance of RP I have ever seen on this server, bar none, came from when a halfling priest of the Lawgiver (what the hell) declared quite verbally "Your god is false" and without missing a beat, uses the corpse of his fellow Lawgiver on Lizuca.
You want the Morninglord temple to be less silly? Then what is needed to be done is that we all endeavor to be better roleplayers and report stupid behavior like what I described up there to the DMs when it shows itself. You want a place for corpses to be organized in the sanctuary? This already exists, and it's called a graveyard. Why corpses are even in the temple all the time is beyond me. That's how you catch dysentery.
