Lua API (Guild)

I would like to suggest adding a few extra functions.

1) Function Guild.AddMember - Gives the ability to add a member to the guild.
2) Function Guild.DelMember - Gives the ability to remove a member from the guild.
3) Function Guild.AlianceCreation - Create an alliance between 2 guilds
4) Function Guild.AlianceDestroy - Destroy an alliance between 2 guilds

Any other function which can be usefull in terms of guild? 🙂
