Bot to pass your messages to groups on its behalf
ChtrBotI can pass your messages to groups on my behalf. No one will know who really sent them.
Just invite me to the group, and all its members will be able to send messages to it on my behalf. If you add me to several groups - no problem! I'll ask you to select a chat for every message you send me.
If you find yourself sending a lot of messages to single group, you may want to try "instant send". Enable it in settings, and I will not ask you to select chat for every message. Just don't forget to switch them with /active command :)
P.S. For bots developers. I also supposed to be the cool tool for developing bots for group chats: you create a chat with me and your bot, and can post messages for your bot from two users with single telegram account. However last telegram update has made this feature unavailable: bots don't receive messages from other bots anymore.
Hope telegram will add a setting to change this behaviour, and feature will be available again.
