Instructions:
1. Add bot
@thefeedbackbot to your chat group and make it admin. Bot needs acces to the messages in the chat group, otherwise it will not be able to determine authors to receive thanks.
2. Send a message "/token" to bot's private messages (not to the group chat). It will give you a token.
3. Add this token to your chat group name at any place (you can just add it the end of name). This is needed to confirm you're admin of the chat group.
4. Send a command "/link" to the chat group.
5. If all goes well you will receive another private message from the bot - it will return you a link which you can use to see statistics.
6. You can return your chat group name back.
7. Enjoy!
