I have activated the extended profiles feature. So far I have added a free text area labelled 'About Me'. See my profile for an example. You can edit yours by going to My Profile - Profile - Edit Profile.

I can also add sections for images, links, dates and checkboxes (which are sort of like a poll I think).

We may have had this set up prior to the upgrade. If you think any info has been lost from your profile let me know and I will see if I can find it.
