I have to add onto Lee's comments about "Add As Friend".... I also accumulated over more than a year's time a solid "Friends" list and it got that way through only one method - if I played a round with someone and we had a nice game AND everyone acted honorably. It's formed a nice "Core Base" of reliable players - and I furthered that when forming my Country Club Membership base.
EVEN SO - I will ALWAYS enjoy meeting new people and playing a round - and will often accept invites when requested for a game - though bear in mind if I do not reply or DECLINE it is often because I am either AWAY from my computer or wrapped up in something else.
I do get the stray "Friends Request" from someone unknown to me (questing for the "Socialite Award"?). I tend to decline these in order to keep "known reliables/enjoyables" on my list. On occasion, I HAVE added a friend solely because of productive exchanges in the FORUMs. In short - if you want to add me as a Friend - Invite me for a game! (NOTE: The second you start panhandling or asking for gifts, it is Curtains for You.... LOL)
