In addition to our community on http://discourse.appimage.org/ (which is a combination of a forum and a mailing list) we use two chat channels:

#AppImage on irc.freenode.net. You can use any IRC client such as the XChat AppImage or the web client at https://webchat.freenode.net/?channels=appimage to connect.

This is a real-time chat, which means that you will get answers instantly if there is someone around who can answer them at that time. So hang around for some time, most activity is on the evenings (European time zone) and on the weekends.

在QQ和TIM上有一个对AppImage感兴趣的华人社区。 这不是AppImage项目的官方部分，也没有得到正式的支持，但是可能会对中文用户和开发者感兴趣。 在“搜索组”页面中输入组号 274328087, 然后通过单击“加入”按钮将请求发送到组的管理员。

There is a Chinese community interested in AppImage on QQ and TIM. This is not an official part of the AppImage project and not officially supported but may be of interest to Chinese language users and developers. Enter the group number 274328087 in the "Search Groups" page and then send the request to the admins of the group by clicking on the "Join" button.

You can use your browser to connect. https://gitter.im/probonopd/AppImageKit

This is not a real-time chat, which means that you will get answers after some time (can be hours or days later) once there is someone around who can answer them.
