Wow, here's one that really fell through the cracks...
 

Global Flags...I was all campaigning to get a handful of them, then it kinda got forgotten about.
The idea was that there'd be either one flag or one string per server that can be seen on any server...string works best, but I don't wanna push my luck...it'd be like some NPC on Classic sets
global.classic=sword3.png goldshield2.png head30.png gray gray orange gray darkblue body.png 3 3 3 100 true
Then another server, at their option, can read in that string and do something with it...like if you go on Enigma and you have global.classic=true, your character gets to start with their classic stats because they defeated the final boss of Classic or something...

The exact implimentation would be up to the local LATs...like getting the global.Delteria flag would be meaningless on Classic, but on Faheria it's good for a free cookie or something. You can save your Bomy data on G2K1 and carry it to G2K2, but on Classic you get nothing. Stuff like that.

*shrugs* I'm rambling, someone help refine this idea?

I think this idea is pretty good, and shouldn't be too hard to implement. :)
I guess I made a comment like that before, but ... x.x

Yes its a thing we already thought about, because
in the next Graal version there is also a script command
to directly warp a player to another server without the
need of pressing F8 and selecting the server.
Sharing flags or similar things is currently not so
easy, because they are saved locally, but that can
be changed

Haha, instead of warping people to onlinestartlocal when they are causing trouble on 2001 we could send them to Unholy Nation. :D

Yeah, I don't know how messy it would be...but some things, like the account name, password, subscription time remaining, those are stored globally...if there's room for a few more bytes, one boolean flag per server...^__^
It would be vaguely limited, as I could only set global.classic;, but on G2K1 that could be worth a Classic God hat, on Delteria worth a L2 Sword, depending...
*shrugs*

Staffs of different PWs could also make a deal, so if someone is jailed on the one PW, it gets stored in the global flag, which makes him also jailed on the other...

...nah, that's what global bans are for.
