srry: you're right about the entity guide. ant wanted to make more pages like it (for listing categories, etc), and i strongly opposed. i'm sure the entity guide page will be changed, and those big icons are just a placeholder until we make some new graphice for the categories
as for bbcode on the front page, i've left it the way it was before: only img tags are visible on the front page.
daubster: the shoutbox live page needs an update, this should be fixed in time.
hunter/everyone: the bug stopping externally hosted maps from being added to the vault has been fixed.
