The site needs a simple method of downloading archived versions of the software. I would think most people are reluctant to make regular changes to their production server. I have myself been as far back as 3 revisions of the openfire/wildfire server. Luckily I download the releases as they come out so I have them. Even more lucky is I now have a sandbox server to test on. I have seen many requests in the forums for older versions of the software (Openfire and Spark). It would be a great service to your customers to provide a consolidated download site for these.
