Yes there is signs in Minecraft Pocket edition
in regular minecraft you have to "summon" herobrine. in xbox 360 edition you can unupdate the game to summon herobrine but i am unsure if u will ever see him i know you will see burning trees and will find missing torches and stuff and possibly creepy signs in random places. i have not played pocket edition lite but if it is connected in any way to 4j studios then it might have been removed. you can always try summoning herobrine and find out that way.
No, they cannot read signs, although I wish they could, but unfortunately they can't. Sorry :(
It is the default skin for new players. You can always change your skin :P
"pocket veto"
A pus pocket under the eye lid can form if if there is an infection in and around the eye.
Nobody knows.
You can, but only using punctuation. I use dashes and pointed brackets: --------> <-------
the control the player no but to type on signs and titles yes.
No, everyone should be able to write on them however the server you're playing on may have a plugin preventing you from using signs
You cant make a couch as such, but you can place a stair block and than put signs on the sides.
I don't understand what you mean. E-mail me at katamari123456789@yahoo.com and give me details about your question.
