[Snort-users] Question on new rules naming

Actually, I don't show an issue.  Shellcode.rules is empty now. 

You should remove it locally if your rule update system is not.

Many of the old categories are now empty, so if you could double check, that'd be great.  Our rule pack today will also contain a bunch of further-emptied categories.
