Calendars
Event Calendars and Date Pickers are often required to enable visitors to understand what events are on where and when, get further information, plan their schedules, or book facilities or shows.
Chat Boxes
Chat Boxes enable visitors to your site to chat between themselves, something that may make your site more attractive to users. You could, for example, implement a chat box for your website “members” if you are an Association or similar, allowing for meetings to effectively take place on line.
