i dont want to remove the players that dont play nomore. i want to remove the big list of pepole that i have an invite to play that never accepted or not on friends list no more??

If you have already unfriended them then support will have to remove them. Other wise you can remvoe them from the "my neighbors" tab at the top of your game. 

Those are good to have. When I need to clear grass, cactus, thorns, cut trees, unwither crops and such those are the ones I can use. :)
