I've had several people ask me how to add comments to their blogs. Since my system isn't accepting new accounts, try this: Documentroot.com was advertised on this very site this morning and that's how I found the link. That link is an advertiser's link but it gives credit to Google so feel free to use it. I don't know anything about the system since you have to sign up for it first, nor am I able to help you install or maintain it, but if you're desperate for comments this may be a decent resort.
