If you mean "leave Community", then go to the FamilySearch.org, sign in, Click on the circled question. A box opens, click on the question that asks how to join Community. In that area, the first section tells you how to join, the next is how to leave community. Let me know if that is what you mean. Not sure if you meant leave Community or Family Search?

It took me a while to find this. Go to My Groups, Click on your group which I assume is FamilySearch Family Tree, go to the bottom and click on All Discussions, now next to the blue box labeled New Discussion there is a cog, click the cog and it says Leave Group.
