There's a slight chance that recent browsing of the forums has resulted in you receiving a Too Many Connections error page. This is a byproduct of the web site experiencing some growing pains - it looks like March will be the best month ever for unique visitors, and we seem to be hitting some limits on the database server. We're investigating whether this can be resolved quickly through some software tweaking or if it will take a bit longer with upgrading hardware.
The database server has been set to accept 5x as many connections, so it looks like this issue has been resolved for at least another year or two.
