I might be able to contribute an article/essay on becoming
fluent in one's own conlang, based on my experiences and
a survey of other people who have done so.  I haven't
forgotten my intention to do a talk on that subject at the
next LCC assuming I'm able to go, though I haven't yet
found time to do the survey.

I personally think that would be a wonderful addition to the ASP.  Make sure it is very practical, with heaps of things to try and advice from those who have succeeded.
