There isn't a lore-approval system any more. The reason RP ideas isn't regularly processed is because it isn't meant to be, like the Tech Ideas and General Ideas it's there for players to leave suggestions for the broader server. It's not the Lore Forum of old.
Back when we had Emote default, whatever you emoted happened. If anyone just came up with something fun someone else would call powergaming and demand approved lore. You couldn't just be creative, you had to have your idea hammered out to the last detail and then signed off for balance, lack of contradiction with other things and non-abusability by the LMs.
Previously, the LMs had been a writer team. They occasionally helped rittsy (who's been in charge of server lore since forever) pick out nice things from the Lore forum to make official like lore for soulstones, tidied the lore up where it had gotten knotty and most importantly wrote stuff for events and map transitions. They were a small, innocent staff team that only did good things that nobody on the server objected to.
With the playerbase demanding lore for anything that was being used against them (and sometimes even things which weren't), the Lore Team's role changed. It became their job to process the Lore Forum, to determine what was fine and what was too powerful, too powergamed or, straying into more dangerous territory, "didn't fit the server". Creative new things had to go through them first, if they didn't, other players would complain about not having lore, and there were LMs who were also GMs that would enforce the removal of lorebreaking things. Naturally, players resented having even their very RP reduced to yet another effective app, and the Lore Masters became the bad guys. This is the time where "Make Fun Not Lore" comes from.
When PvP default hit, I created the rules for the Mechanical Standard. This was designed to eliminate the widely resented Lore Approval system in the same way Ski and Cruz's MA removal was meant to do the same for magic. The idea was that the game mechanics would form the baseline for what you can do, like on the Aegis map where their wasn't an official Lore Team (everyone who did lore and story work was also a GM then). With a few clearly specified exceptions if what you did followed the mechanics of the game and wouldn't otherwise be powergaming, you could just go ahead and do it. You were free to be creative then and there. The Lore Team then would go back to its original role of making LotC a more colourful place, in addition to answering player questions and helping players fit things into the mech rules.
Of course, this message, despite being publically posted, hasn't quite got around to this day. People still see the Lore Team as either the Fun Police going around lorehammering people's RP (they don't even have the power to do that) or the Lore App Team, hence player indignation at the standstill of the Roleplay Ideas forum the Lore Team isn't actually meant to review.
There's also a hefty spanner in Mechanical Standard's works: magic.
When Ski_king and Cruz removed the MA, their intention was (correct me if I'm wrong here ski) to do the same thing to magic that mech did to lore, as long as you weren't powergaming, you could do what you liked with magic. No subtypes, cast whatever you want and explain it however you like. This didn't quite happen in practice. People who had fought their way to the top of the MA weren't at all happy at everyone else getting what they got for free and thus fought to maintain the MA structure as much as they could. That, and the problem with doing this with magic is that magic doesn't have a mechanical standard. The baseline then became the existing magic lore and the magic guides. As these were organised into subtypes, so magic stayed subtyped and has to this day.
The solution to this is Telanir's magic plugin. When this is completed and put onto the server (I believe the intention is to install it in 4.0 but if it's nearing completion I think it should be released sooner) it'll finally become possible to remove the magic system as the ex-MAT intended, and I greatly hope that's what's going to happen. If you've got that spell, explain it however you want to, it's balanced by the mechanics of the magic plugin.
But for the meantime, I'm not entirely sure what to do with magic posts. I can go through this the way I'd have gone through a lore post of old and suggest fixes for every problem I can find, or I can help find an alternative that makes approval unnecessary. Up to you.
