Profile Type Specific Register Module And Perma Link Questions

Hi All,

Now that I am starting to dig deeper into ES I have a few elementary questions.:
First: I have found something kind of odd. There is a module that seems to allow registration to a specific profile type. When I enabled this and tried to test it, it actually selected the default profile type with an option for the user to switch profile types and the user then has to select the profile type that the module was set up to direct them to. Am I missing something in my configuration as I would love for that module to actually direct the user to that specific profile type's registration without them having to select it manually from a list. I fear it could confuse the end user.

Second: Is it possible to have the user's perma link url NOT include the word "community", but rather simply be http :// mysite. com/profile/user_permalink?
As of now mine are showing "http ://mysite. com/community/profile/user_permalink" I tried to change the Community menu item and alias, but got a 404

Lastly, is there a way for the admin to push a post through all user's feeds?

I realize these are very basic questions and I hate to waste your time with them....Thanks so much in advance :-)
