If you don't mind me asking, is there a reason you'd like to leave the Community? Are you getting too many email? If that's the case then you can quickly and easily change that so you don't get any (or very few messages from the community) To do this click on your profile icon (top right on the page) and then Preferences. You can then change your settings to fit with your needs - personally I only get one email from the Community a day, but you can also change it to none.
Hope this helps and hope you might consider changing your mind about leaving. We're a pretty fun group and are always happy to help!
