Here's how to add a signature
Someone showed me how to add a signature and I'm passing the info on.
Go to Settings top of page right side
Then go to Edit Signature, bottom left side
Then where it reads Preview if you have something there remove it
Now right below you should see the word Font, Size and a white box with only a
small triangle
click of each one of these and a drop down menu comes up, choose font,size and color
(sometimes you need to click on these a few times for menu to appear)
Now type what you want your signature to read
Scroll down to bottom right hand side and click Save
Its not as fancy as some signatures I've seen but its better then nothing.
