Forums Scripts & Popups Intercepting my own text (etc.)

I succeeded (not so difficult anyway) in intercepting msgs from other ppl with:

on ^1:TEXT:*:#:{
; .....
}

and it works great. I was wondering, is there a way to do that to my own text? I tried creating an alias for /msg (which would overwrite the default one), but it didn't work.

So simply put: I intercept text msgs with on ^1:TEXT, and format them the way I like, is there a way to do this for my own msgs?

TIA,
