As I said in my previous post above, if your IRCD is same as mine, there's OWNER and FOUNDER status, with 2 different access. You didn't say whether your IRCD splits OWNER and FOUNDER into 2 different things. Do these both give you a reply?

/chanserv help owner
/chanserv help set founder

It will help you to be more knowledgeable about chanserv privileges. You should do "/chanserv help" to see all the topics, and once you see the topics you can get more info about with "/chanserv topicname". Also, there's "/chanserv help set" to see additional topics.
