I have a list used to request assistance from my team. We have 8 content types for specific types of requests, to ensure we get all the information we need to fulfill requests of those types. We also have a "General Request" content type for everything else, with only the basic fields like Requested By and Target Date, and then a text field to describe what they need. The General Request is the default content type, because none of the more specific forms would be appropriate as a default. However, we have observed that we are starting to get a lot of requests that use the General Request option even when they need one of the other types of assistance, because it's the first option in the list and they don't want to scroll through to look for the "right" option.
I've been asked to move the "General Request" option to the bottom of the list in order to encourage use of the other forms (we're also generating some volumetric reports on the different content types) and to rename it to "Other", but as I mentioned, none of the other content types would be suitable as a default.
The list is in a web part on our site's home page. InfoPath is not an available option. An approach that can be done with code in a CEWP would be preferable to an SPD-based method, so that other content on the page can continue to be maintained in the browser.
