Who are you?

[SEAN_MCAD]

I have quickly looked at the FAQ's here however I havent found the answer to what I am looking which are questions as such
What is a EQ2 Interface?
Who are these developers who are developing on them?
As a developer myself where do I get started as in what is method being used for these interfaces? Exposed web services? reflection? what what.

These are the types of question I have for now. Leanring how to install maybe later

Thanks
