In his last comment before wandering out into the wilderness for a few weeks to clear his mind and recharge, Kryten mentioned a holiday promotion by SoftMaker.
If you go to their “Load and Help” 2013 site and download free software until Christmas Eve the company will donate money to charity. The rate is € 0.10 [about 14¢ US] per download.
They have an office suite, FreeOffice, available for Windows and Linux boxes, and some Holiday fonts for Windows, Linux, and Mac.
You provide a name, e-mail address, and country, so they can send you the registration details.
It is marketing, of course, but not as obnoxious as the last thing I bought on-line showing up in an ad at half the sites I visit. [I bought it, you tools! I don't need to see it again, OK?!]
