I want to share my Steam Account:
Well, post your Steam Accounts here.
I'm afraid to post it public:
If you are afraid to share your account name here, then you can request people to PM you their Steam Account(s).
This will allow people to add you if they want to.
If you are to request others to PM you their Steam Account(s), then you should also add some information what kind of GameTypes and other useful information.
So people can "get-to-know" what you like and are interested in. This will allow people to find the "right" person to add
