i m new for the blogger ~ i have a lot of questions ~
what's <!-- begin code provided by createblog.com --> and <!-- end code provided by createblog.com --> mean

I think they are just the opening and the ending of the script.

^ Yeah, it's placed there to show you that you got it from cb.

No biggie.

erm. in html
if somethign starts with <!-- and then ends with --!> it doesnt show up

the same goes for
//this message
/* and this message

:]

hehe...That is just something that explains...doesn't affect the whole script. quite useful too in some ways. like when you're copying that script, u'll know where it starts and where it ends...hehe
