Only two problems I’ve noticed are onn the homepage I think when you click on a link to a form thread (in the list on the right) it should take you to the first post of that particular thread instead of the last post.
And when viewing someones portfolio the text tends to break through the bottom border if there is too much.
I’ve only tested these in FF3 \ PC
I’ve just made a purchase, even though its shown in my account. Its not showing the purchased image on the product discussion page, (apologies if this done on a cron job every few hours or so).
