Forums Scripts & Popups Adding automaticly a dot.

Hi!
I'm using mIRC 6.14 and I want to have a script that does this:
When I write in a channel and sends my msg I want the script to automaticly add a dot after the thing I have written.

Example:
In the channel "#oki" I write "ok, thanks" and sends it and the scripts adds a dot to the quote and when everybody recieves it it looks like this - "ok, thanks."

Is that possible? I hope you understood what i meant.
