ok, I have this small idea in mind, but I'm sort of new in msn scripting language, plus, I would like to get guidance in this. here goes:
I would like this script to open a small text file in a certain directory ( which is frequently updated, from an external application ) then i want to read the last line in the text file, and update my personal message with the last line read
any suggestion, any help, any resources ?
a small example will be helpful alot, since I'm new to scripting in Messenger Plus
thanks in advance

My Facebook Status Script (linked in my signature) does a similar thing to what you're asking, except taking it from an RSS feed, not a text file.

It should be easy enough for you to alter to do what you want it to do.
