A few section's missing?

Hey guys, i just got back from work.
Just thought id pop by and see whats happening.
To my sight, some section's have gone?
Eg: Buy & Sell Section's aswell as the Gaia section.
Anyone know why this happened?

Announcements, announcements, announcements.
What a terrible way to die.

Just some revamping going on. Among a few other things.
