Xenforo looks great but, having only worked with WordPress, I have a few questions before purchasing: My host provider is HostGator. Do I just install Xenforo in my public_html directory? Do I need to worry about MySQL or PHP? Are XF add-ons the equivalent of WordPress plugins? Are add-ons added to widget areas (like WordPress) or do you need to code? Can I display forum-specific sidebars (i.e. display diaper ads on baby forum, tune-up ads on car forum)? Is there a visual editor for writing posts or pages or do I need to be proficient in bbcode? Doex XF offer a forum backup tool? Thank you.
