When the user selects to edit their profile in the front end, they are presented with a form that includes a number of sections, some of which I would like to remove...for example details of their own Blog. We are not allowing them to establish a separate blog, simple to post as authors in categories established for everyone on the site.

Can I remove this section, and maybe others, such as feedburner, SEO and Google Adsense as these sections are way beyond the knowledge and understanding of the average author.

In essence I just want them to be able to modify their account and add/edit their biography.

So how would I achieve this...there doesn't appear to be a setting for changing this.
Many thanks, as aways,
Andrew
