Not all tabs are linked with plugins. You can create tabs using CB's tab management. Think of user created tabs as "CB fields containers". You create custom CB fields and put them into user created tabs, and you publish these tabs wherever you wish to on the profile.
Just download the documentation for the CB version you're currently using. That's what you're paying for, and it should all be in there. If you have any questions, just ask.
Hi Rapunzl,
you are right,
i am using J! 1.5.6.
Nevertheless, CB Profile flag is working ok. But I am just using it in a hacked way (using a personal image instead of a flag) to make appear information on the user profile. Until now, no problem. Wait and see.
Nothing's left for invention.
Keep your ears and eyes wide open !
