I have a quick question related to the Public and Author.
In a lot of the documentation there are references to public and author instances and different path to each one of them and also different activation processes, however when following CE setup video tutorial i have created my own module which serves the content.

So my confusion is what kind of instance have i created, is it Author or is it Public?
When i create a page i can access it via the following URL:

localhost:8080/myProject-webapp/pageName.html

this tells me its a public instance ...

However i can access my adminCentral module by following the below URL:

http://localhost:8080/myProject-webapp/.magnolia/admincentral

Now this means its an author instance .....

Nevertheless, how do subscribers fit into this picture? I have read this article but it just made me more confused of what a subscriber is and what it does and why i need it.

Sorry for these very basic questions, im sure there is relevant content out there explaining all this but i am struggling to fid it.

Many Thanks,
Ged
