That sounds like the Masako I know. He quit the CBB (the conlanging forum where I post) a few years ago.

Carl Buck has always loved designing scripts or adapting scripts for new languages, including his own conlangs. Qatama, a conlang he abandoned several years ago (whose Romanization was originally very Klingonish -- D for a plain old /d/, q for /k/, Q for /q/, etc.), had something like three or four different con-scripts that could be used to write it. On the CBB, I once commented, when discussing how my focus in conlanging was not on scripts, "Unlike such posters as Masako, I only have one alphabet, abjad, or syllabary for each language I create, if I've developed one at all". Masako replied: "I sorta almost feel like this is a dig at me, but whatevs". (I replied: "Oh no, it's not a dig. I FAIL at con-scripting compared to you!")
