[org-mode]: repeating task in every Mon, Wed, Fri at 18:00, need help with sexp

Question

As I had written in title, I need a little help with improvement of this sexp:

* TODO remeber about thingie.
  SCHEDULED: <%%(or (= 1 (calendar-day-of-week date)) 
                    (= 3 (calendar-day-of-week date)) 
                    (= 5 (calendar-day-of-week date)))>

Now it shows itself in the following days, but I would like to change two things about it:

• How can I also schedule on specific hours (i.e. 18:00 - 20:00) in the following days

• How can I made this task repeat itself, just like it repeats itself with

  <2010-05-13 Wed +1w>

  (by repetition I mean something like it automatically logs the closing date and time and comes back to the TODO state).

I will be grateful for any help.

Thanks.

* TODO remeber about thingie.

  SCHEDULED: <2012-05-11 Fri 18:00 +1w>

Unfortunately, you cannot use diary-sexps for repeating TODO items in org-mode like that. The work-around is to create three repeating TODO items, and use the normal org-mode date expressions, not diary sexps.
