I did this on the RC 4 but can't remember how to get custom profile fileds showing under a users name when they post. Can somebody give me the code please?
In the postbit template, add $post[fidX] where X is the profile field ID. But you should be careful because those variables aren't htmlspecialchar'ed, which means if there are HTML code in that profile field, then it will be displayed as HTML on the postbit.
