Message deletion

Sometimes, you have to delete a lot (and I mean a lot) of message at once. That's where /purge comes in.

Note: this requires you to be an admin in that group!

delete all messages

If you reply with /purge to another message, this will delete all messages which have been sent after this certain message.

delete all x messages

Just reply with /purge <int> to another message, where int is any number. This will delete as many messages as you have specified.
