I'm looking to make a site that extends the Groups class into an Organization class. I want to do this because I want to draw a distinction between user created groups and official organization pages. I figured that extending Groups was the best way to get all the Group functionality. 

There is an example in the docs that shows a simple example of extending groups and it includes the elgg_register_entity_type call. I looked it up and it says that this is to register the entity as a subtype for search results. I do not want this functionality. So I'm going to just declare the subclass as it's own type. I just wanted to make sure there were no extraneous repercussions. Would leaving this call out of the class definition mess up the system in any other way?
