The easiest way to know who is playing is to put month and year after date eg April 21 or 4/21. I have a lot of inactive players. It took me ages to go through their Profile pages to check this out. I find I send more eggs to people who indicate they are still in and not waste sending eggs to people who are no longer playing the game. I know some players by the gifts they send me but a lot of people have similar names. The easiest way to make sure people know you are current is to 4/21, 5/21 etc on the 1st of each month. Works for me and others.
