# MyOggRadio is an open source radio station directory. Because this matches
# well with streamtuner2, there's now a project partnership. Shared streams can easily
# be downloaded in this channel plugin. And streamtuner2 users can easily share their
# favourite stations into the MyOggRadio directory.
#
# Beforehand an account needs to be configured in the settings. (Registration
# on myoggradio doesn't require an email address or personal information.)
