// Note: where a translation string contains {{x}} (where x is a number),
//  it means that a parameter can be inserted. Please make sure to include these
//  parameters in the appropriate location in your translation.
// It may be sensible to add comments after your string to indicate what its parameters mean.
// NOTE: parameter numbering starts at 0 (unlike previous versions, which started at 1).

// Translations can be requested by sending a link message on the SLOODLE_CHANNEL_TRANSLATION_REQUEST channel.
// It is advisable simply to use the "sloodle_translation_request" function provided in this script.
