Hello Chris Douglass,
You can have this functionality with Sitefinity.
For example, you may create a user control, which could be placed on the public page. The user submit some information in the fields, hits a Save a button (just an example) and the content goes in some module. It can be in any module actually. If you want to save information in the Lists module, then the Lists module API would be of help:
Let me know on the exact functionality you want to achieve, and I will elaborate more about it.
