Linking acc to Gmod

wen i link acc to gmod website it says that i dont have gmod but i do, i have gmod 10 and it says

That account doesn’t seem to own GMod.
If it does - it’s set to private, please make it public for this process and try again.

How do i link it?!!!?

the account that you’ve specified in your profile here ends up with an error message. you may have the wrong idea of url, hold i’ll get pictures.

edit profile

specify that up there

Go into Steam > Community > Edit Profile, and set it to public

This is invalid now considering there is a new way to link your account. Go to www.garrysmod.org and do it nao!

As for you soderholm, look in the picture, it says public… derp
