OK, this is REALLY important. I've been a subscriber to MSDN for several years and have received hundreds of CD's from our friends at Microsoft. The CD's are starting to threaten my survival in my office. I have boxes of the old ones, now outdated and of no use to me but protected by my license with Mr. Gates. I hate to just throw them out to take up space in the local landfill. I'm also concerned about the legal issue of throwing them out and having someone who's dumpster diving find them and use or resell them.

Does anyone know an environmentally friendly and legal way to dispose of these things?
