Totally off-topic - or maybe not: Open Office 2.0 has been released. It's not quite as off-topic as it may seem: CheckerBoard is freeware, and so is Open Office. I'm always on the lookout for decent free software, and Open Office certainly belongs into this category (much more so than CheckerBoard). If you're tired of paying Micro$oft for annoying you with talking paper clips, try this!
While I'm at it: If you're looking for a decent program to create installations, try Inno Setup.
On my computers at home, I also use free antivirus software: Anti-Vir personal edition on my desktop computer and AVG free edition on the laptop. I haven't made up my mind as to which one is better.
When it comes to graphics, I use XnView.
I edit my website with Arachnophilia. But I'm not 100% satisfied with it - it's very no-frills, and you need to know your HTML to use it.
How about you? What free software works well for you? I'm only interested in productive software like the above, not in games like CheckerBoard :-)
If you know of a great free program (no NagWare or trial versions!), please add a comment!
