If you used Flash and wanted our people to see your product,
forget it. Note that some companies do not permit the use of Flash
products. Using Flash sidesteps nothing; it does limit your
potential customer base.
As for JavaScripts being enabled, there isn't much you can do
other than state "JavaScript enabled" as part of your product
requirements statement. You could use a script to test for state
and if not enabled default to a page that lists your requirements.
A quick search on the Web will yield many hits/samples.
