Plugin source code and contacting plugin authors?
I am trying to determine where to find source code for Plugins or whether it is even available? One specific plugin is the "Sight Reader Midi" plugin developed by DonH. I see no way to post a non-bug related message to the plugin developer.

Plugins are located in the folder ...MuseScore 2/plugins. If you open the plugin creator from the plugins menu then click the folder icon, this folder should automatically open. Open the plugin and you can then see the code for the plugin.
If you still need to contact him directly. He has been on this site in the last month or so. You can click his name then click the contact button to send him an e-mail and see if he answers.
Source code for plugins is always available. You may try to contact the authors via a PM (here via https://musescore.org/en/user/35966), if they haven't disabled this.
