Whilst we are at it a sort feature for product registrations would be nice. By date, by alphabetical order, also group by product or serial number. BTW it seems to generate the product list everytime (long pause) so I suspect it needs some caching introduced.
It's maybe too late but I really do recommend
DotNetNuke which is opensource and can be downloaded via
codeplex. You can have a site up and running in 15 minutes. It saves you a lot of custom scripting (you can write your own customized modules for it or even adapt other peoples source code). It's really expandable and cheap to maintain (and runs on ASP.NET/C#/IIS/SQL Server) and kicks the living sh*t out of Wordpress. Everything is modular in approach even skinning. Developers love it as well as consumers. There is something for everybody and there are providers for more or less everything.
