Avanquest Software, UK is giving away free licenses to use their otherwise commercial software, eXpert PDF Pro. The software lets you manage, create and edit PDF files with ease, besides having a fully functional PDF reader of its own. The complete set of features may be viewed here. It even comes with a good piece of review.
You will first have to register with them after which you will be able to view your license key.
Catch: the license is for version 5 of the software, the latest version 6 having already been released. Nevertheless, a versatile software the older version too is, as I find out.
Here is the direct link to download the file. Registration is still necessary, though, to receive the license.
Godspeed
