can i link 2 bot on two different servers and then from leaf bot if someone user press something send the message to hub bot and the hub bot underestand the specific user who tell something like the user in same channel
like: leafbot: user1 hello (msg on hub bot's channel)
Are you talking of something like relay-scripts (where talk in one channel is relayed through the botnet to another bot which speaks in another channel)?
If so, most relay-scripts can work cross-server without any problems.
