boonex/dolphin.pro ? reverse-engineered prompt

Build me a social networking website platform like Dolphin.Pro where I can turn features on and off with modules, so the site can grow into whatever community I want. I need the basic stuff for members too, like signup, login, profiles, friends, messaging, search, comments, groups or pages if they fit, plus common community features like blogs, chat, polls, events, ads, and classifieds.

Make it support multiple languages, let me switch between design templates, and include an admin area where I can manage site settings, users, modules, and translations. It should feel like a real community platform, not just a static site. If it helps, use current docs or examples online for anything unclear.

I also want it set up so it can connect to mobile apps later, and the code should be organized in a way that makes it easy to add more modules and customize the look and behavior without rewriting everything.
