Q: How many guild “grades” are there and what are they for?
A: Currently the highest achievable grade is 3. A guild is grade 1 by default, and has the privileges to recruit and kick members. A guild graduates to grade 2 when enough contribution points are collected by its members, and can then purchase a guild emblem, elect a leader, and participate in Circle Zone Scramble GvG games in Giga 4 part 2. A guild graduates to grade 3 the same way, by collecting more contribution points. There is currently no extra privileges available to grade 3 guilds.
