I use the following combination:

In the "Perform" section I have:
/timerAlive 0 500 //mytime

While the alias "mytime" is:
/mytime /msg $me This is to stay alive at $time

(OK, I scripted it a long time ago and could be done in one line in the Perform section:
/timerAlive 0 500 /msg $me This is to stay alive at $!time
)

/msg could be replaced with /notice if you so desire.

The function of this is to perform a regular action over your comms link (some ISPs have a 20 minute idle timeout), and to let the chat server know that you are still "alive", not just some ghost that hasn't communicated for a long time. Some chat servers Ihave used had this problem.

Simple, small andeffective.

Oh, and the $time at the end is just so you can tell one message from another after a long period!

Cheers,
