I want to CHANGE the second variable. In my corrected example
you return the first variable. What do I specify as the return state-
A few simple questions. Does the added filter function get inserted
at the apply_ filters statement? Do the variables get changed at
the apply_filters statement and not before or after? A function can
only be removed if a do_action is inserted in the function? Finally
a function with do_action inserted can be processed first with low
priority with a user function and the primary function will not execute?
Beg my indulgence, I hope that is not too many questions but there is
no specific documentation in Codex except add_action and add_filter.
