You cannot email things to the forum, you have to post them just as you have been doing with the words you've been typing here.

To post your screenshot here - Position your cursor where you want it to appear within your typed words. Look at the top of the box you are typing in. There's a button for Bold, Italic,... then on the right hand end there's a little icon supposed to represent a picture. Click on it then click on Browse then select your file & click on Open then click on Upload.
