Pretty much what Justin said... clearly you haven't been around on the net much because many of the problems we have here are prevalent in every online community. I recently joined a forum, totally unrelated to props and almost had to laugh as I can virtually place names of members from our forum on members from this new forum based on their attitudes and demeanor!
The things with the cliques and elitism lately really has gotten out of control. It is absolutely pathetic to see how some people choose to behave and that some people have such little self esteem and worth that they have to play "god" in an arena like this to make themselves feel like they have some value. The worst part is that it is generally (here and everywhere else I have gone) the most talented among us who feel the need to act the most childishly. However, as long as people condone/overlook those actions, worship those people and give them power, they will continue to misuse it. That is just the way it is. I think it is unrealistic to expect the administration to do something about it. They can't force a certain individual to sell a particular item to a particular person. They can't force people to like one another or be gracious. They can't force people to realize the board and people they continually poop all over is the same board and people who have given them their "celebrity" status in this tiny sliver of society. It is very sad but I have seen it again and again here and in many other places.
In regard to the newbies... there is no reason to be rude to them, but the fact of the matter is that it is pretty arrogant and self-important to come here to TDH and expect to be hand fed the information that is already readily available on this board. If you are too lazy to simply do a search, why should I take MY time to type it all out for you? Again, there is no justification for old members being rude about it, but it isn't out of line to tell a newb to use the search function. It is an inappropriate sense of entitlement to think that and old timer should spoon feed you the things you can easily find for yourself.
On a final note, I really think it is silly for you to leave in a huff because everyone won't play the way you deem they should. If I did that, I could pretty much just shut my internet connection off and never go online again. There will always be those who choose to be rude, unscrupulous, liars, pot-stirrers, and trouble makers. Some are clever enough to stay just below the radar and so they will be here. Just ignore them and enjoy the good things, the positive contributions, the people who are truly trying to help one another. There are still plenty of those people here and this is still a great community. As much as we wish some would just fade away, they won't and even if they do, there will be others who will step in to take their place, but by letting them drive you from a place you love, you only give them more power.
