Archive reminder

To enable archive reminders set an offset (in hours) in config/config.json for archive_ctf_reminder_offset. Clear or remove the setting to disable reminder handling.

If active, the bot will create a reminder for every bot admin on /endctf to inform him, when the ctf was finished for the specified time and it should be archived.

Example (for being reminded one week after the ctf has finished):

{
    ...
    "archive_ctf_reminder_offset" : "168"
}

Log command deletion

To enable logging of deleting messages containing specific keywords, set delete_watch_keywords in config/config.json to a comma separated list of keywords. Clear or remove the setting to disable deletion logging.

Example

{
    "delete_watch_keywords" : "workon, reload, endctf"
}
