Lindrian, I\'ve done my best to do what you asked :)
It works now so that it doesnt make entries of one url more than once :)

You\'re welcome. And what you do is:
if ($1- !isin $read(yourtxtfile.txt,n,1)) {
The ! infront of isin, means if its not in the file, it\'ll add. just to give you a hint, u might be able to figure it out yourslef ;p.
And the $1- means the first word and the rest of the sentence.

1) The dots... well ... I sort of... like them :)
2) I fixed the () on the if statement
3) I was thinking about checking if the link existed or not and then posting accordingly. I decided against it because I didn\'t want to get too complicated and because I don\'t have that much experience to do that. Maybe someone can help me with that.
4) about using $fulldate, I went with what you said. But I think its just a matter of personal preference if someone wants to change that, its not that hard.

Thanks for the comments Lindrian

Oh and btw, since u can edit comments (argh x.x) ill have to post a second one, well, why dont u make a if statement to check if the youtube file is NOT in the txt file, and it will add it. No need to have multiple urls right ;p?

And u know, u can use $fulldate instead of \"YouTube window opened $day $+ , $date $+ , $time\" etc.

I see, looks kinda usless to me, but someone might need it.
1) Whats with all the dots?
2) your missing () at the starting if statement. This one:
if %tube != on {
