Chat messages support links, embeded video is supported an it’s possible to call in another site member to the chat using @mentions.
I’ve introduced rudimentary threads support. The behavior is that a new message, posted more then 15 minutes after the last message will be marked as a new thread. All messages posted after that initial message will be regarded as part of that thread. After 15 minutes the thread will be deemed closed and if posting of threads to group activity is enabled then all messages in the thread will be posted in a single activity update. I’m expecting this functionality to change as the plugin develops.
Currently the chat supports text chat and the sharing of links. I’m interested in adding further features but would like to see some user requests for the same.
This plugin was originally created by David Cartwright and has been forked by Venutius. It includes an emoji set which was sourced from WP Emoji One by Monchito.net.
This plugin runs from your own server, no chat data leaves your site. This has has the benefit of minimizing your exposure regarding user privacy and GDPR, however chat will be as responsive as your server and can be laggy because of this. User conversations are stored for one month then deleted.
