Is it true that the only way to confirm that a WSS site is in use isvia the Email confirmation, and not actual use of the site?
Email is the only way we check with the owners to verify site usage.Presumably an IIS log analysis tool would also do the job.
Why not use the Usage Analysis? From that I can see when the last visit was to the wss site in question. I check it manually through the browser, but presume you could also do this through code.
Unfortunately, if you turn on the option to verify site usage, the SiteCollection owner will have to respond every 90 days that they are stillusing the sites even if they just posted to it yesterday.
I've heard of people using the global.asax events to determine who iscurrently logged-in and what sites are in use.
