Welcome to the world of internet forums. All forums are likes this. Longtime members get accustomed to doing things a certain way, and they don't like to take time out of what they are doing to deal with someone who is new to a site. Most don't like newbies at all. However, new members here or anywhere shouldn't be put off by the snarkiness of certain members. There's always longtime members who are willing to point you in the right direction, in a kind and helpful way. Just ignore the ones who would rather call you lazy and dumb and move on. Don't judge the entire site by a few members.
Anyway, when I first started coming here, I tried to find a glossary of terms. I knew all the airport codes, but not the day to day abbreviations. The first place I looked was for a stickied post going over the glossary, as it is in most forums. I never thought to look under HELP, assuming that would be about account and contact help. See, how would you expect a new member to decipher a PM like that if they had no idea where the glossary was?
Perhaps a stickied thread or a thread going over everything newbies should know would help out both longtime members and new recruits.
One last thing... I really do appreciate everything that is contributed by all members here. I have learned a lot and saved a lot with this information, long before I became a member. Flyertalk as a whole is extremely helpful.
