This little website tracks whether emails sent by you were opened and read by the receiver. It also provides the recipient’s IP Address, location, browser details, and more.
This handy site lets you print out web pages while skipping ads, off-topic banners, and other useless info.
This service allows you to save full web page screenshots, not just of the visible part of your screen. Paste the URL into a special form and save the resulting .jpg image (other formats available). If the process is taking too long, you can send the image to your email
