I've had a look around and I can't see that this has been asked before so here goes.
I know there is a two-per-hour limit on PMs. The address bar allows for multiple recipients so say, just for an example
I put 5 recipients in a PM and pressed send and off it goes, do all 5 get that message? do only the first two get it? does it roll the second lot of two over to the next hour? or does it chop off anyone after the first two? I could ask the people I sent a PM to but that's another PM!
Thanks, and apologies if I've gone full Kermit the Frog on this!
