Howdy Peter,

In the interest of not being preferential of one of your choral works over another (because I've really enjoyed them all if in different ways), I'll also mention here about ChoralWiki. It's located at http://www.cpdl.org/wiki/index.php/Main_Page and is for use as a repository of public domain choral music, whether it be original or arrangements of other public domain works. I do think you should submit some of your works there. (I tried searching for you, but you didn't come up, and thus I presume you are currently unlisted.)

ttfn,
Sherry
