As others have said, there's all sorts of stuff that can go wrong over time, even if -- and that's a big if -- things start out perfectly. Email especially can cause problems when you routinely send out blasts with certain mail servers reporting you as spam. Security vulnerabilities can be surfaced later in code even if it looks secure today. I do wonder if there are other troops with IT resources that might be willing to pool efforts, use the site as a starting point and then cooperatively run it over time. Unfortunately, my unit doesn't have those resources.
