Today I realized there is nothing more annoying than phone numbers in email signatures that do not properly select / dial from smart phones / blackberries / etc.
People need to lose the parenthesis when putting there phone number in the signature!
(555) 555-1324 when clicked on with a blackberry or otherwise will only dial 555-1234
If the number was displayed as 555-555-1234 or 555.555.1234 there would not be a problem.
Why can't people give up on the parenthesis?
Also on this note, don't include an image in your signature. Some of us do not like seeing an attachment on every email. Just type in the company name!
