Question: How long is the term for moderator? Is it one year?

Answer: 
There is no specific term - it is until a moderator steps down or is removed.

Would we be interested in an unofficial community standard for that? Kind of a polite, "we go for six months at a time and then rotate it up among those interested?"

... Though our current crowd of pro tempore folk has been pretty awesome.
