Redemtech's green tech giveaway

You could win some green technology for your favorite school or non-profit with Redemtech's "Serious Good" contest.

Here's one way to build a Twitter following. Technology asset disposition and refurbishment company is running a "Serious Good" contest in which it will give away $10,000 of refurbished equipment to a non-profit group, non-governmental organization, school or public library.

The catch is that you must submit your nomination via Twitter and follow Redemtech's Twitter feed (their handle is @Redemtech, which you can find here).

The systems come from the company's Red Rabbitt refurbished brand line, and they include Microsoft XP Professional and the Microsoft Office Suite.

Nominations will be accepted through Nov. 30. The contest rules are here.
