I thought about this for a bit in chat and semantically, I can't imagine a time someone would write *'s at the beginning of their post (with a space afterwards) and not mean to effectively write something in the possessive. E.g. *'s got a boat* - Fred's got a boat.
I dont see why this only needs to be for IC, sometimes you want to talk possessively about things in an OOC manner.
Got something to say?
