Creating a poll via the app is simple. Enter your question, an optional description and any possible answers for the question you have posed. Don't worry … Read more

A few weeks ago, Facebook introduced the ability to sync photos taken on your iPhones, iPads, and Android phones to your Facebook account automatically. Jason Cipriani describes how to enable the feature in "Getting started with Facebook photo sync on Android, iPhone."

Do you find that you are forced to repeat yourself throughout the workday? If this repetition occurs via e-mail, then you might give GmailWiz a try. This Chrome extension adds up to four buttons to Gmail that send automated responses.

Today I found a feature in iTunes I didn't know existed; the ability to set up a monthly iTunes allowance for specific Apple IDs. Brilliant! … Read more
