You do realise that if a=99, then by definition a!=65 and a!=1 don't you ?
Also, when matching a substring, "1" will never 
ever match a 2 character string - "1" != "01" and 
"1" != " 1".

Perhaps I misled you by not noticing this mutual 
exclusion earlier, but you need enough to make 
each class used in a pool mutually exclusive - so 
you don't need to mix allow and deny within one 
pool.

This is still mixing allow and deny in one pool. 
It probably won't do what you expect.


I know there are people on here running CM setups 
(I'm not), hopefully one of them will chirp up 
because from seeing threads in the past, I'm sure 
it wasn't as hard as you seem to be trying to 
make it. I think they were probably using vendor 
class IDs to differentiate between their kit, the 
CMs, and end user kit.

Thank you, yes that's exactly the situation. It's 
not just the top posting, but I see it regularly 
on lists where the top posters also never trim 
what can end up being a LOT of redundant text - 
sometimes including a dozen copies of the list 
footer !
I have also seen cases where the respondent has 
top posted, but then put more in interleaved text 
- and I've missed it because I've not seen any 
need to scroll down through what appears to be 
pages and pages of dross.

It all comes down to people doing their best to 
make it easy for people to help them.
I'm with ESR on this :
http://www.catb.org/~esr/faqs/smart-questions.html
People are free to ignore that advice, but then 
I'll feel free to not put the effort in to 
helping them. In a lot of cases it's just that 
they've never had this explained to them - so I 
try to give people the benefit of the doubt and 
give them a humorous pointer to the errors of top 
posting.
