You know, I don't think it's a bad thing that people ask questions - even if the questions have been asked and answered before. Forums are dynamic, not static. New members join into the conversation all the time, and each makes a valuable contribution.
Before I found this forum I stumbled upon twistypuzzles.com, and I was thrilled to find that there were other people like me who liked puzzles. I joined the forum right away, but once I read the posts I decided not to bother because I'd never met such a mean-spirited group of people in all my life. Every time a new poster posts a message, all the long-standing members attack him. If the new poster uses the search function and posts questions or comments about an older post, he is attacked for dragging up an old post. If the new poster simply asks questions or comments without researching the archives, he's attacked for not using the search function. It's like being caught between a rock and a hard place - the bottom line is they just don't want newbies there. That's fine - I was really glad to find this forum where people are a whole lot nicer.
