I've been very pleasantly surprised with the number of people downloading the forms based authentication web parts I created. I hope you find the code valuable. I've also received via the comments section several questions about implementing one or more aspects of the solution. I haven't had time to answer many of these lately and so I thought my loyal readership (up to 3 now!) deserved to know why.
I've been working with the Community Kit for SharePoint team to create a new open source (more or less) SharePoint template for Internet/Extranets which includes as a major component a much more advanced Forms Based Authentication solution. This project is on CodePlex at http://www.CodePlex.com/CKS. You'll see that the teams have already released an Enhanced Blog Edition. In the CKS:IEE along with web parts for user self registration and password recovery, we're looking to add administration of users and roles, automatic configuration of FBA, a membership approval process, and many other features that will make using FBA with SharePoint easier and faster. In the meantime however, that means I won't be able to get to all of your questions about the web parts from my web site. I appreciate your comments and readership and will circle back to try to answer your questions when my load lightens up a bit.
