Thanks to the timely comment from Scott Watermasysk, the developer of .Text (which became the blog engine for Community Server), we've got our technical glitches sorted out and everything should be working normally.
How often have you had a software problem and gotten the answer from the person who wrote the software, directly on your website? Doctors don't do housecalls -- it's nice to see that developers do. Thank you, Scott -- your fantastic level of service is part of what keeps me so happy with this product.
