Just throwing it out there but, some networks use the operpasswd module, which if you oper up on the wrong network, they can see your oper login and password, which can be detrimental to you and your network if you have not configured your oper hostmask correctly, so I don't really recommend auto opering on networks. Also if you use the same password for everything they will then get website logings nick logins and much more. So always think about it carefully before you do it.
