Specifically I'm looking at the "Resource Info" section. 

On the right there is an option to Add Resource.  In this screen, you can also edit the existing questions by clicking the Edit option.

For example, this drop down menu, you can add or remove to the highlighted area.

2 things I need to know:

1) I can't seem to find a way to delete the actual resources themselves.  I can add news ones or edit existing, not delete.  Is there a way of doing this?

2) In the Service Catalog - Additional Fields, there are limits to how many text, drop down etc fields you can create.  Are there similar limits in the Resource section?
