Thanks for the concerns.

ez.org does not have to go commercial to continue to operate. The banner ads (that are only going to appear on the top of the main page) are an experiment to see what type of revenue could be generated. More revenue = bigger bandwidth and more disk space.
I have a large number of pictures of canard aircraft that cannot be loaded to the site now and Terry Schubert continues to add to the CSA archive. These jpgs require a lot of disk space and a require substantial bandwidth to download.
I hope the ads do not cause too much of a problem for anyone. If they work the trade off for a faster site with more content will be worth it. I tend to ignore banner ads on other sites so I may not be a good judge. How does everyone else feel?
If you are not seeing any ads at the top of the main page that means that Google has run out of ads based on the content of our site. I've seen a few ads: Amazon, Controller.com and Garmin.
