wasq is correct. Use the
www.ahevents.org url and you will only have to login in once. When you go to
http://ahevents.org and click the login button a window pops up which allows you to login. This login is done via a cookie / session var being set. The cookie is being set to ahevents.org. When you click on another link in the menu, it changes your web url to
http://www.ahevents.org/... which the cookie / session tag no longer is valid for. Thus causing you to have to log in again.
