[Pan-users] Two newbie questions - sorting in header panel, pan newsgroup ??

[Bill Case]

Hi;

I am relatively new to  newsreaders and pan.  I would like to do two 
simple things but there seems to be no manual.  Suggested reading anyone 
(I have read through the pan site)?

1) I would like to set 2 criteria for sorting in my header panel; first 
by watched threads (at the top) then everything else afterwards by 
descending date and time.  How can I set this up?  If I use filters 
where do I find filter construction info or manuals?

2) I can't find any 'Pan' newsgroups to subscribe to.  I am I just being 
stupid?  Does anybody have a recommendation for a good 'Pan' group?

Regards Bill
