Disconnect: No family sharing..

[forest crest]

I told a friend of mine to enter a server so she could download the server addons before we play.

This is what she send me afterwards.

Is she playing Garry's Mod through Steam family share? Some servers may not allow such players to join, instead requiring the Steam account to actually own the game.
You should ask the server's administrators about it, and check their rules (if they have any shown).

She is indeed, playing via family share.
And by the looks of that "No family sharing.."
text, trying to talk about it to the admins
will do no good.

Yeah probably best just find another server to play on that allows it (if purchasing the game on that account is not possible).
