points bug and some feature requests

bug:

points for likes and correct answers are not being credited to posters

feature:

1.  there's no helpful attribute.

2.  there's no way (for me) to delete a message.

3.  sorting (eg, by latest) should be 'sticky' and not require repeated reordering after a forum is loaded.  (and what does sorting by 'relevance' do?)

4.  clicking reply to a anything other than the original thread post, brings up a one-line input text field, inadequate for most responses.  i must edit that one line response to format all multi-paragraph responses so they're intelligible.

5.  some way to easily stop following a thread from that thread's list page.

6.  add message numbers in threads (so previous messages can be easily referenced).
