edit .emacs and then ....

This is a real newby question. I have a load of buffers in emacs and I
edit .emacs with some new cool macro or what ever. To get the new code
working I could close and restart emacs, but I will have to re-load
every buffer. Is there an easy way to either 1) get the new lisp code
working without closing and reopening, or 2) close and reopen and
still have all the same buffers available so I don't have to open
easch manually.

peace
Dave
