Customizing About page and other pages

[zogstrip (Régis Hanol)]

• ability to write some long text with markup (images, emails, phones, other website for contacts)

I reckon this is not the best UX, but have you tried changing the description site settings with your content?

• remove automatically created list of admins and moderators (can be done via css currently).

May I ask why would you want to remove that crucial piece of information?

I’d like to be able to add links to other pages in this menu.
