[Zope] Rating site.

Hello, I'm trying to build a rating site for medical software which will be identical in functionality to the http://www.icewalker.com and/or http://www.zope-treasures.com site except for the purple colors. I'm currently running squishdot, which I could use pretty easily if you could add extra fields associated with a squish article, but so far I haven't had success in that direction :-( I've asked the zope-treasures people for their code, but they are running Sybase behind theirs and I'm using Zope only. Does anyone know of something that I might use for this? Or if it is possible to add fields to a squish article? I know PTK will have this, but I'm facing competition so I need to get something working soon. -- IV
