Can someone tell if there's a tcl script, where it greets a user in my bot, which can be customised ? In another words, to set an info line to an user in my bot

For example, a user can change his own greeting whenever he joins the channel. What I am trying to say is, if 2 users with +o flag, and both of them can have different greetings. It's not due to the flag(s) they have.
Anyone know of this script, kindly tell me abt it. Thanks.

Oh yes, one more thing. What's the uses of botnet exactly ? Does it means that, whatever i type in the console, all the linked bots will respond to the command i did in one of the bot's console ?
Pls do enlighten me
