[leafnode-list] reading another group

[Roi]

hey

i have my config setted with groups pcre to read about 3 groups
and really in Pan when i fetch all groups from local server I see those 
3 groups
and they are getting updated every fetchnews run.

Now i want to add another group , added it to the pcre line in the 
config file
and touched and empty file in /var/spool/news/interesting.groups/
(owner setted to news (as the other files))

but fetchnews doesnt see it, groupinfo file still has no record for the 
new group.
In pan I tried reading new groups but no new groups appeared.

How can I add a group now for fetchnews to retrive ?

Thanks,
Roi
