cookies in custom web page

hi all.
ok i recently made a page:
5thclan.150m.com
as u can tell i used frames and directed things to my forums: 5thfreedom.proboards28.com
in order to post u have to log in, but when i log in, it closes the frames and just directs to the 5thfreedom.proboards28.com. and when i do log in and go back to the site, i dont stay logged in. is it not keeping my cookies? i made this all in html, and if theres a way to make this work plz lemme know.
