[rules-users] "or" not working

[Mark Proctor]

You will need to give more details than what you are doing like the 
actual syntax of your rule. It looks like you are using a DSL, I would 
suggest you look at the actual DRL that DSL is outputting, then if you 
still have problems send that to the mailing list.
