@nguyendam I understand that you want to make changes to your site but the support questions you are asking all are about customising your community and/or using 3rd party plugins. We (the dev team) are often more focused on squashing bugs or adding new features to CBOX, we simply can’t help you with all of these customisation requests. When our community grows and we have more people using CBOX, the chances that our community can help you out will increase. Until that time some of your questions might remain unanswered, I hope you understand that.
There is a lot of information available about both CBOX in our documentation and on the various WordPress resources on the web. Learning WordPress (theming) is fun and will allow you to make more changes yourself. If you get stuck you can hire a developer to do this for you and point him to our documentation.
Good luck!
