Can anyone help me with tips or urls etc to help me alter the Member List ? When my users are entering more text that usual, the member list gets very crowded, with text overlapping.. it looks horrible and very unprofessional.

And on a similar note, i would love to restyle the search results page. It needs more contrast in alternating rows and more space to help the eye find the subject matter.. 

many thanks, drew..

The search results and members list page are the same template. Just letting you know that any changes you make will affect both views.

thanks Will.. can you let this AS newbie know which css to start looking at?

Drew,
Firebug for FireFox is your friend when it comes to identifying and testing CSS changes through DNN.

You can use it to "see" which css classes are being applied to which elements on your page (right mouse click on the section and select "Inspect Element".

Then you can adjust you CSS and see the changes.

All of the AS CSS is in the module.css and the specific theme you're using. If you don't want to create a new theme you can simple copy the adjusted CSS classes into either your skin's CSS file or paste them into the portal.css through Admin | Site Settings | Stylesheet Editor.
