Brian:

Do you notice how I used the simple perfect to denote that it is where I normally live? I am getting my CELTA. Do you notice how I used the present progressive to denote that this is happening now, but that this is not necessarily where I live?

In any case, I hope this clears things up for you. If you still have trouble reading, you might want to check out a few books on the subject and get some practice.

Brian, what I notice most of all is that from your response that you seem to embody a particular type of teacher that I hate to have as a colleague. If you speak this way to your students, I doubt you'll get much repeat business. Hey, if you wanna be exploited by Pagoda, be my guest -- you both seem to deserve each other. I'm just offering a warning to balance your promotion. By the way, from your silence, I have to assume I was correct regarding the long-term split shifts there.
