Eco-Terra - Error in the town greeting message

When members of our town log on to the server, the greeting message,

«Welcome to Eco-Terra, where the future is your’s».

is shown. If the word «your’s» could be changed to «yours» so we don’t come off as illiterate swamp bender hics to any new members who might join us, that would be nice. I REALLY hate having to be «that guy» but…actually, no I don’t. Grammar is important and the incorrect use of an apostrophe in our town greeting triggers me as an English major.

An apostrophe is used to either indicate missing letters in the middle of words or phrases (such as «can’t», «won’t», «don’t», «doesn’t», «hasn’t», and so on and so forth) or to indicate the possessive. For example:

«That is Bwake’s tea leaf.»

«This tea leaf is Bwake’s.»

«Zuko’s honor is an illusion, and so is death.»

However, personal pronouns (words like «I», «you», «he», «she», «it», «we», «they») indicate the possessive by becoming a new words entirely. In the context of our greeting message the word «you» becomes «yours» as it indicates the possessive for multiple people.

I apologize for having to be a grammar nazi, but as previously stated, grammar is important. May the wind always be on your back.
