Don,

Please add my personal thanks to the chorus for your work and devotion!

As for file formats, PDF's main advantage for me has been print readiness. While the newer versions of Acrobat keep adding functionality, printing is still the main appeal. Limiting editing capability might not serve the legitimate uses members might put the information to. It would add protection from nefarious lurkers, if that is an important concern.

As for wasting bandwidth, banning me from posting would be a good start.

My two cents, Clark
