A whole bunch of "easy" questions (yet very important)

Hi,

Instead of asking one question, why not send a shopping list (grin). These are actually a bunch of elatively easy questions, most of which should be somewhere in the "where is the html doc so I can insert this manually" area :)

1. How and where do I change the <title> tag
2. How and where do I punt i more meta tags <robots>, etc
3. How and where can I edit and add fields to the "invite a friend" form
4. How and where do I add options to the contact us form (such as radiobutton choices)
5. Where and how do I change the background colors of the blocks (hopefully in one place and in one line)

6. Can we allow/disallow the use of certain videofiles (like flv) and if so where and how

7. Can groups have subgroups or categories within the groups and how do we set this up so users can implement/modify this?
8. How does a user upgrade a group member to group moderator (in order to allow for multiple moderation or leaving the group for someone else to own/moderate)
9. How can a user make the background of the profile blocks transparent so the background picture shows through?
10. Can we we allow/disallow the use of certain functions (such as video upload) for individual users (no we are not going to make this an upgrade member facility)

Okay, as you can see most of these questions are user(community member) driven.

Hopefully this will bring some answers :)
