I received an email from someone indicating that the commenting system is a little spotty--that in order to comment they were required to register.  This shouldn't be the case!  I've tested everything and assume it works properly, but if you run into any problems like this, please send me an email at my gmail address, glynnish, and let me know what you're experiencing.

Does anyone else have the same trouble with commenting? 

UPDATE: I believe I've corrected the problem.  Let me know if any of you still experience difficulty or receive an error indicating you must register to comment.
