By mistake I erased Sally's latest query msg, so I write from

* do I learn others' conlang?

Not in entirety, but I do check out (as time permits) phonologies &
grammars, and try to get an overall feel for the lang. I enjoy the
interplay of sounds and meanings ("phonotactics", "morphophonemics")
rather than phonology per se. Altho my bent is towards alien langs, I
enjoy all kinds of grammars: loglangs and naturalistic langs.

But if do find time in any considerable measure, I would want to learn
some natlang: at the moment, some "Amerindian" lang, of which I happen to
know next to nothing!

* have I created a script to go with my conlang(s)?

No, but I expect to do so soon!
