I found the Ultimate Theme Guide for Designers
documentation to be a pretty useful resource but I must say I had a hell of a time figuring out how to get to the HTML of any of the forum content that didn't exist inside the default.master.tpl file.
The ultimate theme guide does make note of the existence of Views but it only covers how to style them with CSS, and says nothing about modifying their HTML content. The only place I found that mentions modifying the views is buried in the similarly-named A Quick-Start Guide to Creating Themes for Vanilla
documentation where it notes that the views are buried in the Applications/Vanilla folder and should be copied over to your theme folder for editing.
I think it would be incredibly helpful if the ultimate theme guide included this information so that people don't have to go hunting all over the place just to modify some HTML on their forum. I'd imagine this is the kind of thing anyone wanting to create a theme would need to do so I'm surprised its not made more obvious.
