First, your nickname -- the name you're already using -- must be registered with the IRC server. It's simple, you just type:

 /msg NICKSERV REGISTER [password] [email]

^{example: /msg NICKSERV REGISTER abcd9999 bob@gmail.com}

It seems to need email, doesn't mean it has to be a real one. If you forget your password, eventually your IRC account will be reset if you don't use it. I believe it takes two weeks.

Then let me know, and I'll add access to you for #all

After you have been added by me, in order to OP yourself, simply type the following to log in, if you are not already:

 /msg NICKSERV IDENTIFY [password]

^{example: /msg NICKSERV IDENTIFY abcd9999}

That's it. You will then be able to use OP commands, notably /topic and /kick and even /ban. Please don't abuse them, and if you see them being abused, let me know.
