Garry's Mod - "Friendly" Achievement

I created this group to get the "Friendly" Achievement in Garry's Mod, where you must play with 10 of your friends.
If you are interested then join and follow the following rules so we can increase our success:
- write one comment (by doing this, you agree that other people can add you)
- add the previous 10 persons who wrote a comment
- join the group chat so the communication is easier
- invite friends to this group, who may also be interested in this achievement
- create a discussion where you figure out a date

When we got about 11 players we will add eachother and go to a server...
Feel free to join if you already got this achievement and want to help others.

Thank you! :)
