Add ajax fields to a tab in the user profile

[toodimm]

Hi

I'd really appreciate some guidance on how to add an ajax field to a new tab. For example, the 'about me' tab contain a number of fields that can be edited using ajax. I've added a new tab to the user profile and would like to add my own ajax fields to it.

Anything to get me going would be welcome, links to appropriate pages on the api would be the most helpful.

Thanks
