I didn't realize Paul was talking about me, and for some reason missed Eric's quote. It was probably due to me being a bit discouraged, so I wasn't thinking clearly and was mildly distancing myself from this. That is no ones fualt but my own, and seeing this gave me a chance to look back and see that people still wanted my contributution so thank you. I'm ready now, I recently got an account. However, I have no clue where to start, but I'll see what I can do.
