As I've mentioned, I regularly read the World of Warcraft Official Forums, to fill time when I'm away from home (read: at work) and have a few minutes to spare.
The Guild Relations board is a gem of a board for Officers and Guildmasters and those who aspire to those positions, with a constant smattering of topics that cover a wide variety of challenges that guild leaders come up against in the process of running their guild.
Occasionally, a non-officer type wanders into the forum and posts about some injustice applied to them by the leadership of the guild they're in. Feedback is probably not what they're hoping to hear, but ultimately it's what they NEED to hear. The Guild Relations regulars are not going to hold you while you cry, they're going to give you some tough love without resorting to name-calling or flaming.
A thread going on right now has some really good information in it for folks who are new to guilds or new to their current guild and are looking to become a respected member of the team:
Thread name: Unreasonably kicked out of a guild?
The Original Poster (aka OP) explains how he joined a guild, socialized on the guild line, then asked for help and was told folks were busy, and in an instance. After a few days of this pattern repeating, he was booted from the guild and put on /ignore.
Some well-stated response quotes from the forum regulars I'd like to pull out of the thread:

"As a note. Guild want people who help more often then they ask for help, usually at about a 4:1 ratio. ie, help other people 4 times before asking for help. If, on the other hand you ask for help four times before helping someone, expect to see the door."

"Expanding upon this, people generally frame relationships based upon a ratio of positive to negative interactions. To maintain a relationship that is viewed as being positive, there can generally be only one negative experience for every four or five positive experiences."
Summary
If you've been booted from a guild or denied entry in the first place and have no idea why, consider reading some of the following threads and considering every single one of the responses the original posters got when talking about their own dilemmas:
