Thank you, you are very generous with your praise. I'm happy to help where I can.
As for the forum, we don't get a heavy amount of posts. We are a fairly small community. When it comes to getting responses, it has a lot to do with getting to know the right sections to post things. Most users will only look in sections that interest them, so when something gets posted in the "wrong" spot it tends to get ignored.
As for your other posts:
Unfortunately I don't know anything about Ted Tseng. This forum is specifically for ocarinas made by STL, so strictly speaking we aren't supposed to discuss other makers. You won't be able to get much information on ocarinas other than STL.
For your request on I am the Doctor, I will look put it on my to-do list but I can't promise anything. Complex songs like that are much harder to fit into the range of the 12 hole.
As for the ocarina network, I think you are only allowed to reply to posts for the first little while? After you have made so many replies you can start creating new threads. It has something to do with foiling spammers. I'm not certain because I'm not an active member there.
