Hello, again it's me... I want to know how to show some fields in a page for a certain group of users. Let me explain better:

Actually I'm using the Member Profiles module to get the people registered/logged-in and to show some special pages to the logged users, but I want 4 things...

1. How can I show some fields of the page only for logged users??. I mean, I have my homepage template, but I want to show a poll only when the user is logged, but, if the user is not logged, the poll will not be shown. Is possible to do that?

2.How can I add a lightbox(or similar) to silverstripe to show some little images/links in the site?

3. How can I add an avatar to the member profile? Is this possible? Can I add custom fields to the registration page (Like the one that I like to add, the avatar field )?

4. How can I list all the users? and, the last one, how can I show in the profile page, show all the comments made from this user???

I'm in a hurry and any help will be highly appreciated

Thank YOU in advance!!!
