I just found a nice page with a list of female webdesingers: http://www.leemunroe.com/25-hot-female-web-designers. So I was curious and looked at some of the listed pages and further the suggested pages in the comments.
My personal selection is here – and I hope there will be more suggestions, too. Maybe we will reach the 100s? Sure. Give them to me! Use this as your showcase.
