I have been trying to lock down the site better because of some bad behavior over the last several weeks by some odd attempts to penetrate off-limits parts of the site. If you feel like you were locked out in error, send me an email to the link on the header of the site with your approximate location (e.g. city) and the approximate time of hitting the site and I will unblock you. Also, any info on the pages or files you were trying to access in vain when you were locked out would help me too.
In other news, I am still waiting for Disqus to get all our old comments loaded and back online.
