My questions: do I set the cookies to site? And how and where can I edit the write.cookie to include everything I need (never wrote a cookie myself so please take that into consideration when explaining).
Bit of bad news for you, Ranko; as far as cookies are concerned those three subdomains are completely different websites and will not be able to share cookies, even if you set them to website. If I recall correctly, there was a topic recently about "hacking" a cookie so it could be shared across subdomains which you should be able to find with a quick search.
As for writing the cookies, have a look at this tutorial and also at the doCookies function in inc_func_common.asp.
Search is your friend “I was having a mildly paranoid day, mostly due to the fact that the mad priest lady from over the river had taken to nailing weasels to my front door again.”
This may do the trick for you (read it all); if not, post back and I'll go a-digging again.
