help with leveling a new guild

alright well i just moved my main character from a level 25 guild to a level 6 guild. i look forward to helping this new guild level and grow. i really am just looking for advice on the quickest and best ways to level the guild. is it through guild raids and 5 mans? or is it through guild achievements? or is it through another way. any information and advice would be helpful and appreciated. i know this is probably elementary for most of you but i am really ignorant of this information. thanks for your help.

* Do quests (dailies & normals, so level some alts!)
* Do Guild runs in heroics
* Do Guild raids
* Do Guild PvP

Basicly, do stuff with your guildies, or simply do quests. I'ld say instancing & raids goes fastest, but as you need more people for that, it might kinda be a skewed view.

The Guild Challenges grant a huge amount of guild experience which is independant of any weekly cap you might have.

thanks for the advice and help. i do appreciate it.
