Possible Fail point:
- Chat windows probably fails when one joins too many Organizations.
Solutions:
- Remove that blasted chat window. (After all, all we need is main and npc!)
- Make it option which Organzation chat windows are present, limited to (say) 5 at a time.
Yeah, I figure that'd about do it.
Questions:
About the parent/child Organizations, how do you see that with regards to the chat (One chat, seperate or both)?
With regard to how to make, become a child org and how to leave a parent?
With regard to buying Organizationhouses? parent buys house, child may come in? And how about child buys house, may parent come in or other childs?
With regard to being member of who? (member of child auto joins parent?)
With regard to ranking in both sort of orgs? (high rank parent has more powers then same level child? Or just a whole new sort of ranking system?)

Answers:
Each is it's own organization. There wouldn't actually be a specific system for parent-child relations. The parent and the child would be two separate organizations that players belong to. In most cases the player would belong to both a parent and a child (say the main guild and the crafters section of the guild).
Parent and Child organizations would be completely roleplayed. If a child org. wanted to leave it's parent it would just roleplay that. No need to do anything.
Guildhouse entry would remain a key based system.
No auto join, they'd have to be invited.
Up to the individual organizations
The Parent-Child idea is just an example of what players could do with the more flexible organization system that I am proposing. It would give organizations more ability to be individual. An Alliance could be made of a bunch of Organizations by making another "Alliance" organization and inviting the leaders of all the orgs. into the Alliance org.
It's just a much more flexible system that restricts organizations (or guilds as they are known in game at the moment) less than the current one.
Players belonging to more than one "organization"... these are just evil ideas designed to crash Laanx.
I haven't looked at how guilds are coded but, I'm pretty sure our devs could make this work rather easily. It would mean a small overhaul of the current code but probably wouldn't be all that much work. Besides that the green 'guild' name above a player's head would be removed. Because it's just silly.
