It would be the equivalent of one message, not really an amazing amount to scroll through even in a quiet realm. (I regularly have to go down the equivalent of several pages to get past all the turn stuff) So I am not quite sure where in the world you could possibly be coming from. Furthermore, you keep saying it would be another Ruler Bulletin, but I doubt that greatly. Ruler Bulletin is usually for stuff that you don't expect to have to change any time during your reign. This would be more for stuff that is relevant for a week or two, but you expect to change semi-regularly.
For example, you wouldn't put the unit settings for the army in the General's Bulletin would you? So then why would the Ruler put a tournament announcement or other such stuff in the Ruler Bulletin?
Are you kidding? I see unit settings in general bulletins all the frigging time. Maybe GX wouldn't use it as an extra ruler bulletin, maybe it would, regardless, wouldn't stop others from doing so.
Every hollow message is annoying when logging into with a cell. I don't mind too much on my computer, but on a cell... Tack on a destitute royal message the ruler put there forever ago and that's just a vanity disclaimer, to incredibly outdated marshal standing orders as isn't uncommon, to a few pinned messages you haven't gotten to reply to yet or just want to be able to contact someone with the hot dial... on a cell, it gets really long, really fast. And it pops back every. Single. Login.
Mostly I would use it for RP planning/status and other projects That I want to make sure the players see without beating them over the head with multiple messages. Things like "The SuchnSuch Rp will start on Sunday" Or "Talk to SonSo about your wiki" or anything else that comes to mind that might be a good way to invest players who might otherwise have skimmed through and missed it. Things that should be separate from military orders, yet are pertinent to the realm. I got the idea from "Message of the Day" (MoD) notifications one gets in mmo's if they are in a guild. Yes, we are talking about GX now, but I would love to see more realms get built back up to those kinds of numbers.
Investing new players has been a project of mine for some time now. The number one complaint I've had from new people that have left are feelings of being overwhelmed, unable to catch up or make heads or tails of situations they get dropped in the middle of. I and the other GX players have been fortunate to get a lot of people to stick around, but we have gained and lost over 30 accounts and I wonder how many we might have retained had we different tools to anchor them.
To that end, I find existing methods to be cumbersome and ineffective, and co'opting a marshal's standing orders would only add confusion.
Most people don't consult the ruler bulletin because most ruler bulletins are incredibly outdated and were never relevant to begin with.
For the things you mention, I honestly think the ruler bulletin would work quite fine. Every time you update it, the whole realm gets a notification. If you get your players used to looking there for such info, they'll get the habit of doing it.
Of course, people can get overwhelmed by these things in GX... imo, what you ask for isn't the solution, it's pretty much an extension of the cause. Everything is so centralized. It all seems to revolve about bringing everyone around the Xerarch. It's about those singular events that target masses. If it was all broken down into pieces, with groups instead of a singular whole, it would be much easier for participants to keep up. The more massive you make the events, the more people will just give up and skim through it at best, skip it entirely otherwise. Just like the ridiculous tournaments from back in the days. There comes a point where people shouldn't be expected to read it all, and that people should be able to get involved without needing to start binge reading hundreds of messages per day.
