Hi Jo, you should have, just above where you type your message, and below the Subject box a line of buttons. The last on the right should be a smiley face. Click on that and it gives you a range of similes ::-) 😀 🙁 😐 😎 etc… (Hope we get more in the future!)
At the present time there isn?t a spell checker. I normally type my messages in Word if they are long and copy and paste them in.
kindest regards
David
