Dropbox Dropquest! 1GB of bonus space!
Dropbox is doing a special promotion called “Dropquest,” which is essentially a puzzle game created by some of the employees of the companies. It consists of ~25 clues and for each challenge you successfully complete you get a parcel of bonus space on their server– it totals 1 GB in the end. The challenge is rather difficult, so if you get stuck, feel free to Google “Dropquest hints” or something to that effect– there are loads of forum posts around the web that should help you move on.
If you don’t have Dropbox, you can sign up for free here. Dropbox is a web-based system that uses cloud computing to enable users to store and share files and folders with others across the Internet using file synchronization.
I use it for doing clever things like syncing my Keepass database, sharing presentation files after I give a seminar, and other miscellaneous tasks that require file use between my three computers and iPhone (and it allows me to access these files in a pinch through a web browser somewhere else), but other individuals also use it purely for off-site backup in the event something goes horribly, horribly wrong inside her laptop (since Dropbox syncs with the cloud it preserves a copy of your files on their servers– these files can be restored in the event of a hard drive failure).
New or existing Dropbox users can also increase their space here and here.
