Joys! Another post on the intricate un-wonders of Microsoft Excel. As all those who are unlucky enough to be Excel fiends know, there is enough about it that is a right royal pain in the ass. Anything that can make working with it a little easier has surely got to be welcome. Especially if it's free, given it's not always easy to get employers to actually give you anything involving £, and it feels morally wrong to make a personal investment into the mysterious lands of numbers in squares.

With that in mind, here's the Poorhouse's current top 3 free downloadable addons for others who spend double-digit hours a day inside this most gridular of programs. All guaranteed working for at least Excel 2003, and probably other versions too.

The Poorhouse has a penchant for games and gambling, and where better to combine than poker? Actually, so far, online poker doesn't appear to have quite the fun that real live poker does, but it passes the time better than say an extended GMTV session, plus you can make money. In theory. If you're lucky. Unlike certain forms of betting manipulation, there's no guarenteed wins to be had (that the Poorhouse discovered yet anyway), but there is a quick way to profit in the cash value of items if you're into poker at all.

2plus2, publishers of poker books, have an offer where if you sign up to a poker site and complete certain obligations you get to pick 5, count 'em, 5 books.
