The last big guild was... well... unorganized. Almost the same with the alliance guilds. It was a guild also recruting newbies and was based on helping eachother. I enjoyed helping those who were new to the game - or simply had questions they never asked before - very much, it was great to see how much more fun they had after learning something new and even helpfull and trying new things. I also learned several lessons e.g.: I've never been gvg before. Though we were kind of a PuG with only few guildmembers, I could try something I never thought of could happen before.
I left because of personal differences and - as a result - big argue with the guildleader. Oh my... I was really hurt after that. But I don't hate him or anyone, nor any alliance member. Everyone has his/her kind of playing the game, why try to change someone? You can only try to do your best for your guild, maybe without receiving anything, as long as you've got fun doing it. This is the only way to stay confident with yourself and your guild. If you always want to get double of what you gave, it won't work. And it won't work either, if you cannot identify yourself with the guild's intention on the one hand and its rules on the other hand. If you don't like the system: quit. And maybe start a guild of your own with your rules, with you choosing members and officers... and your responsibility. IMHO that's the best thing you can do.
It was fun being part of that project, even for only that short period of time (i.e. less than 2 weeks, sounds familiar to you, Oh a GW forum?). I even wanted to build a board for what was 'us' at that time. Frequently asked questios were a problem though, but might have been solved having a board to link to and share our knowledge with one another. It never came to happen, as I said, I left. But I would never say that I hate any of my former guildmates, nor do I hate anyone now.
The guild I am actually officer in is not part of an alliance and only consists of three people: my two best and beloved friends and I. We stick together, we belong together. And having a cape prevents from being asked, if either of us would like to join anyones guild.

I'm just fine and don't want things to change ^^
