well if you started your site on help me build my site, then you will have a little bar on the left side and one of the options is widgets and if you click that theres a bunch of things like games and stuff and then a bunch of chat rooms, but if you didnt start your site on help me build my site then you cant use the widgets, but you can visit other sites and sometimes they have links that you can copy and paste chat rooms on your site
good luck
