Creating Auto Ad Post Using Macros

[one1day2009]

I'm pretty new to this site and noobie at using quick macros. I was wondering if anyone can help out writing a macro

macro1
web "https://post.craigslist.org/atl/S/mob/atl" 0x4
lef 36 357 win("atlanta craigslist | posting > cell phones - Windows Internet Explorer" "IEFrame")
key "Test Header"
lef 414 359 win("atlanta craigslist | posting > cell phones - Windows Internet Explorer" "IEFrame")
key "6"
lef 564 353 win("atlanta craigslist | posting > cell phones - Windows Internet Explorer" "IEFrame")
key "Atlanta"
lef 34 458 win("atlanta craigslist | posting > cell phones - Windows Internet Explorer" "IEFrame")
key "Hello"

I need a macro that opens up internet explorer and post same message on different url below:

web "https://post.craigslist.org/den/S/mob/none/x"
web "https://post.craigslist.org/phi/S/mob/none/x"
web "https://post.craigslist.org/sdo/S/mob/csd"
web "https://post.craigslist.org/bhm/S/mob/none/x"

I think i need some kind of loop or something....

any help is greatly appreciated!!! Thanks
