Well, yes & no.
There has been recent discussion elsewhere in the forum on whether or not anarcho-capitalism is an accurate term to use to describe what may also be described as “multiarchy” (which could inevitably lead to Panarchy), eklekltiarchist (the roots of the word can be found here: Petition to stop being an anarchist - #268 by freiheit), which would more or less mean “the freedom to choose rulers” (again, similar to the previous 2 terms), etc.
I myself think that voluntaryism is more specific to what I used to ascribe to anarcho-capitalism exclusively, but would not rule out the others as good choices either. For some, and occasionally for myself, market-anarchist suffices as a term to use instead, as well.
I wouldn’t be against a new Anarcho-Capitalist FAQ (it would certainly help if it looked at all previous An-Cap FAQS & addressed weak areas & recent developments, & to be more up to date), but I would also think that a new “Anarcho-Capitalist” FAQ would be more effective if it utilized a new, more accurate (etymologically speaking) term to describe itself.
