How do I set signatures, avatars and profile pictures?
You can set and change your avatar and profile picture in the User Control Panel. You cannot set a signature.
To select an existing avatar, click on 'Edit Avatar'.
Those directions aren't quite as clear as they might be, though.
First go to Settings <top right of page>
Once at that page, on the far left, scroll down to My Settings, Click on Edit Avatar
Make your choice and don't forget to Save your changes before leaving the page.
You can stop that anytime. It doesn't work with me--far too old and been doing this job for too long to be impressed by it.
Anybody that thinks being macho is only to impress has missed out on an artform that can be very productive and fun. By the way, I am not impressed with your macho style either....kidding, I am a little impressed but, you can stop anytime :P
