BuddyPress.org

hi i have just checked your website. it looks fine in IE8 but the menus are totally not looking good at all in IE7. i have read many places that buddypress support for IE7 is not there at all. the only thing you actually can do is to do some hacks for IE7 this is to say, find out exactly the sections that do not work, then add css tags that will only be read by IE7. lets say for example if you have a problem with width of 1200px and you want the width to be specifically 100% in case of IE7, then do like this

width:1200px;
*width:100%;

in the above case, all browsers will read the width as 1200px but only IE7 and probably IE6 will read it as 100%
well this solution is not a clean and nice solution. but it is quick and it works. i had a similar problem with my site and solved it through this. hope you can use this suggestion.

it seems in your case it is the header that pushes the navwrap down in case of IE7

cheers
