New Modifications to modenacam script

I need to add 1) private message chat (clients can show webcam too) during public chat ( similar to myfreecams) 2) change the number of models that can be seen (display of models instead of 3 models per row, be able to change that number from admin 3) Allow users to find models by location (country, city, zip code) 4) Allow random display of models.(limited by the applied filters, example location) there may be other modifications but these are the main ones
