Not sure if this is possible but i think /tpa should have a time limit to accept. Like one time i needed water from sios so he did the tpa thing, and i accepted it like 10 mins later, which caught him off guard. I think this would really help like a limit of 5 mins or something.
I don't think it is possible... Unless there is a way to put time limits on permissions. o.o I would just /tell or /msg them about it before accepting. xD
It's called seeing it right before going afk, or not being in global when it happened. :b Likely wouldn't have gotten pushed off screen.
There is still /me, alert, the announcements, trade, people joining and leaving, deaths...it WILL get pushed off unless only like 5 players were on...
No one uses /me unless someone popular starts using it. Announcements are every... 10 minutes? xD Trade is usually small during early day, deaths aren't often unless PVP is insane... I've gone 20 minutes with 30 people on, out of global, and still seen stuff.
...two annoucements is enough to take up half of chat, 10 minutes = 3 announcements, one for voting...two for monster hunt, and there is still other annoucements. So no, it's nearly impossible to come back 10 minutes later and see what was there before.
It WAS 10 minutes after. I was working on a farm and mining for about 10 mins and I was like WTF, random TP D: I had requested tp before from him because he wanted to do a water request. So.. Yeah. 10 minutes.
