Really nice looking plugin to allow your wordpress visitors/ buddypress users to chat with one another without having to apply for a third party service. Secured encrypted conversations are really a nice addition.
Plugin has easy integration with shortcodes to display notifications, chat now button or the chat itself.
Attachements are only available through AWS (I get that not using this would overload your database quickly when you have a large user base).
The plugin works really well on mobile devices, allowing users to chat on mobile or tablet screen sizes.
Some bugs are still here, but it is a new plugin (sh*t happens). Support replied within one day, answered all of the questions and provides solutions quickly.
Would have rate 5 stars if the plugin has the option for users to delete a conversation (not only messages).
Would highly recommend this plugin for site owners who want to enable private messaging between users!
