The servers and myself moved to a new location in sunny San Diego, with DSL service from AT&T. This service is 3-4 times faster than the COVAD service I had previously, and for the same price. I was also able to get the firewall fully functional, which has ended the attempts to break in and/or take down the site.
I have been extremely busy with my current client, so I have only been able to work on CMS.NET a couple hours here and there. I'm still working on the core design and code, but am very happy in how it is going. The dynamic CSS system is going to be great for skinning the site. I'll post more as pieces become more concrete.
