Can a blog ever become an event
Installation and Configuration
Its not something that would be too difficult to build as a module, its just where do you draw the line between being able to build a module and building a module and releasing it.
Can you build a module that moves blogs to events: yes, will many people use it, probably not.
Can you build a module that moves images from the gallery to guestbook posts: yes, but will many people use it, no.
Just because we wouldn't build it as a release module, doesn't mean you shouldn't if its useful to you.
