Hm... it looks like you have some indications on hidden threads in
your summary buffer: the "+" on the left hand side and the "|-->" to
the right.

Is this something you have modified yourself (eg. a different format
for the Summary buffer)?  Or is this something that is easily turned
on?  When I do
	T h
I see no such marks.

I really like this behaviour in Forté Free Agent and Netscape, and
wouldn't mind seeing it in my Gnus.  Hm...
	C-h i g (gnus)Summary Buffer Lines RET

Hm... looks like the "+" is just a score indicator.  What about the
"|-->" then?  I didn't find anything matching in the above node.  This 
is the closest I got:

`e'
     An `=' (`gnus-not-empty-thread-mark') will be displayed if the
     article has any children.
