You don't have to include your signature and logo on your profile, but you have the option to add them to your account to be merged into your email, certain reports, etc. You can also use MERGE TAGS to place the signature and logo anywhere you like, on any Service For Life! document here on your account. (read more about those by clicking the link)
1. To add both your logo and signature, navigate to "My Profile" on the left side of the page. Then choose "Account Settings" and click the empty box under Account Logo and/or Signature Image. You'll see "Drag and drop a file here or click." Either drag an image in from your desktop, OR click and browse for the file.
2. Click "Save."
3. Once both are added and saved, they are available for any of the templates that include them.
