FYI - I found the default text size to be way too large for iPhone, iPad and even my computer. There is a global setting for text size shown below that makes the HW site easier on all devices.
Great! Thanks – the smallest size helps on my PC screen too.
Under the “Profile” tab on the screen you show, you can edit your “About Me” text that displays when someone clicks on your member “circle” with either your initial or pic. Although you could keep a full signature with your history here, only a couple of lines of your text are displayed when someone clicks on “you.” Unfortunately, I don’t see a way to “expand” the display to show the rest of the text.
On any COMPUTER → hold the CTRL and hit the plus (+) sign or the minus (-) sign to make the screen Bigger or Smaller. (this works on almost all sites)
