unrealshadow13,
You've posted a lot of questions lately. Clearly, you're interested in and enthusiastic about the game, which is great to see. However, much of the information you seek is relatively easy to find. You could search the Lurker Lounge or Amazon Basin forums, for starters. While I know that we haven't updated the Lurker Lounge front page as often as we could have, there's still quite a bit of information that you can find by browsing through the news archives or by visiting the links to the other great community sites.
In the case of hirelings, a good place to start would be
this thread. Take some time to read through Crystalion's post and the replies. That's a lot of information to digest, but it does answer your question. Plus, by learning more about how hireling exp mechanics actually works, you gain an understanding that is far deeper than you might get in response to a simple question.
I'm not trying to dampen your enthusiasm or stifle discussion. But, I am asking you to make at least some effort to find an answer to your question before creating a new thread. If you do some reading, and still end up creating a thread, chances are the information that you picked up while searching for your own answers will lead to a more in-depth and interesting discussion. So, everybody wins.
Thanks.
edit- now that I've added a sig, I can't remember to stop typing my name after my posts. :(
