There is no notice of clan ops for BO2. They will inform us when they are ready.
If your clan is level 10 or higher on MW3 and you type your clan tag exactly as it is in ELITE then it will turn gold. Otherwise you will have to wait till your clan reaches level 10 in BO2.
i heard the clanops should start sometime next year, but no idea if so is the case!
but since its lagging like crazy in ordinary mp you can only imagine how bad it will be in the clanops
