HyperSnap by Hyperionics is probably the best screenshot program on the Windows sector of the market. It can also be used to run a scanner. Files can be saved in a multitude of file types. HyperSnap can also be used as a graphic file converter.
LibreOffice — is a complete office suite that is Microsoft Office compatible. It's open source, so can be used for free. It functions perfectly under Windows, Mac and Linux, so it's ideal for group work.
Firefox — the most popular browser beside Microsoft's Edge and Apple's Safari. Like most Mozilla products, it is multi-platform: Windows, Mac and Linux and multi-language. It's also free.
Thunderbird — I consider it to be the best email program available. Being a Mozilla product, it is multi-platform and multi-language. There are so may add-ons available for Thunderbird that it can be customised to suit individual needs.
SPAM — not only in your Inbox
SPAM is an American canned meat product marketed in 1937 by Hormel Foods. Since it could be kept for long periods of time, it could be found in all the allied counties, where meat was scarce during World War II. It was presumably the Monty Python sketch in 1970 that led to the new definition of spam as undesirable advertising material that lands in your mailbox whether you want it or not. These two links can lead you to further information: spam.com (can on the left) is pure SPAM publicity; the YouTube link to the Monty Python SPAM sketch (can on the right) is, of course, not ad-free, and may even be outdated by the time you click on it; sorry about that, but you can find it on YouTube easily…
