No. A form's action attribute requires a path or a URL. Controllers are
not usually meaningful paths. Therefore, you should continue to use the R()
function to generate paths.
An alternative to using the R() function would be to generate a path
yourself.
"/page/#{@page.title}" <-- That would work, but I personally recommend
sticking to using the R() function. It gives you the freedom to tweak the
URL structure of your web app with minimal pain.
And how is it sent along? Must the post method have a certain argument?

Let's pretend this is our PageX controller:
class PageX
def get(title)
@page = H.new
@page.title = title
render :page
end
def post(title)
content = *@input.content*
# do something with content and then...
redirect R(PageX, title)
end
end
When someone submits the form you made, the post() method of the PageX
controller will be run, and all the form variables will be in @input.
Hope that helps.

PS: A question for those who have deep Camping knowledge.... Since when
did Camping support "Simpler Routes" as described in
http://camping.rubyforge.org/book/02_getting_started.html ?
I had no idea until just a few minutes ago that capital "N" and "X" had a
special meaning in controller names.
