I think it's been two years. Perhaps it will surprise everyone to know I didn't die... lol
Long story short: I got a promotion at my job while our company became affiliated with some other companies that are loosely affiliated with Nintendo's publishing arm, so I had to be WAY more careful about making my own arrangements/transcriptions of their music. I also got ridiculously busy and couldn't stick around to keep adding content to this excellent website.
I still love doing this, and I've found a lot of value out of making transcriptions - They help you as an engraver, as a composer, and a pianist immensely. I'm afraid the holland_oates89 account will no longer be used, but you may start seeing new sheets coming from a different account from now on. My job is on the verge of changing again, and I think it'll require me to do a lot more composing so I want to work on these sheets to get my chops back. I still want to help with Finale as well, but don't expect me to identify myself as a MakeMusic employee anymore

That is all. I look forward to coming back!
