Just wanted to tack something onto this thread. Many other members have already given some valuable insight to this thread, so just wanted to add a couple more points.
I'm always asking people to THINK a little when they write subject lines - they should be honest and informative. Take the subject line of this thread for example - I had absolutely no idea what I was going to find - I usually ignore subject lines which are vague, it was an accident that I even looked into this thread.
Those that have been here a long time and have contributed are simply going to tune out the many requests asking for the same information they've already typed 100 times. Getting a snotty reply about using search is one up from being ignored entirely.
Too often people find englishforum and think not about what they can do for the community, but what can the community do for them. I can't count the number of PMs I get that say "I want to live in Switzerland, please tell me everything I need to know about permits". I see many posts along the same lines - "I can't be bothered to ask specific questions, or even demonstrate that I've tried to find the information elsewhere, so just tell me everything so that I can disappear and then you'll never see me again".
Learning to use a forum effectively takes time, one has to consider that there is a mass of information flowing into it every day, and your question gets just a few seconds attention (at that). Effective spelling, a friendly and appreciative attitude and good subject lines all go a long way to increasing your "forum IQ". People demonstrating low forum IQ might not find it a very useful tool.
And finally, I often hear it said that "this didn't happen on the other forums I've been on". That's correct - because this place is different than other forums - I think many people already realise that, which could possibly why the traffic seems to double every three to four months.
My personal wish is for (some) people to realise that the internet is not one giant free consultancy service - behind it are people who give their time for free to answer the questions of others, and this is not an automatic right. Unfortunately, judging by the number of PMs, emails and even calls at home (yes) I get from strangers many people feel that the internet somehow owes them something.
I believe that deep-down everybody is friendly, it's just that sometimes their patience may be stretched a little thin. I think I also wrote a little on this subject on this thread .
