Topic: Tag sorting system

How does one suggest that two tags be merged and or that a tag that is misspelled or superfluous be removed?

Also, would it not be of great use to have some sort of hierarchical system for sorting tags?

THAT IS.

= Jizoo
# Jizoo_Everywhere
- Jizoo_Vagoo
+ Jizoo in Vagoo
+ Jizoo on Vagoo
- Jizoo_Butt
+ Jizoo in butt
+ Jizoo on butt
- Jizoo_Head
+ Jizoo in hair
+ Jizoo in mouth

AND SO ON AND SO FORTH.

Also, the ability to relate tags?
