Log in problems?

Have any of you been having problems logging in? A regular – MP – sent me an e-mail earlier today indicating he was having problems. He wrote:

“I wanted to make a couple comments and I couldn’t sign in. Is there another way? Has the login been disabled (temp or perm)? Is there just an issue with my pc (I tried accessing the site via internet explorer, google chrome and firefox; neither one has the username and password fields on your website)?” 

This is one of those situations where it’d be nice to have tech support…. but as most of you know, this is a one-man show (me) and I am not WP or otherwise code-hip.

Any thoughts?
