Guild Experience

I've been trying to do a bit of digging around for information on Guild Experience and Guild Levels.
I couldn't really find much, what I found I'll put here and hope that someone can run with it and build up a guide for this site :)

To create a guild:
Level 20 and pay 50k gold
The daily fee is 900 + 100 per guild level.

Required targets:
6 in 5 days,
11 in 12 days,
16 in 30 days.

At lvl 20 you can have a Chief Officer

1. Your guild capacity increases, eventually up to 50. (I think this maxes around level 25.)
2. You gain officer slots. You can have 1 officer for every 5 guild levels, up to a maximum of 5.
3. You gain the ability to enter guild dungeons at level 11.
4. Your guild becomes safe from deletion (provided SOMEONE logs in at least every 15 days) once you hit 16.
5. At level 50, you gain the guild buff. It starts at 1% to atk and workload, and gives an additional 1% every 10 levels after that. Unlike title buffs, the guild buff is ALWAYS on. It also adds to any running title buff, making it VERY powerful if you can make it to the upper guild levels. (At max, it'll be 8% atk & workload, with you able to slap a title buff on top of it.)

Guild pts are earned through guild crafts, guild op books, town/guild quests and guild dungeons. Guild Exp is earned through regular play just like the exp you get while questing.
Some say guild experience rises faster without guild crafting, some say that it rises faster with guild crafting.

What needs to be added is a table of guild levels for experience, and a table that shows how many guild members allowed per guild level. Would also like some confirmation on earning guild experience, some believe that guild experience stops going up while guild crafting, whereas others feel that it's the opposite way around. lol.

Anyway, if someone could pick this up and run with it, a good guide we will have :)
