As the guild leader of another top 30 guild I just want to pop in here to reiterate a point I haven't seen mentioned which is that a guild doesn't owe a new member anything until they've proven themselves to the guild. Most people understand that when they first join a guild (whether top ranked or not) is like when you first join anything, a new job, a new sports team, etc, this is the time when it's most important to prove yourself as you're joining a group who already has (that's why you want to join them in the first place).
If you can't hit the ground running right out of the gate, you'd better at least communicate that (preferably before you're accepted) otherwise don't act surprised when you're kicked. You wouldn't start a new job and then not bother to show up for the first two days, even if they had a flexible work week.
Ultimately, there's no reason for a guild to take a risk on you if you can't be bothered to communicate with them in an adult manner. Furthermore, being so clueless as to do that AND then come to the forums to bitch about it just proves you're not ready for an active guild. Don't try to pin it on MM just because you didn't step up when they gave you a chance.
