A few days ago, the site decided that my password was no longer valid. So I did the lost password thing, but the email was so long in getting to me that by the time I tried to use it, the code link (or whatever) was time expired. This happened several times, until a few minutes ago I was able to reset my password. It occurred to me in the meantime I had no means of communicating with UMD to try to rectify this matter.
Any thoughts?

There's a "Contact Us" link on the "Home" menu that opens a contact form with multiple options, including account / login problems.
