Why are some people on this forum so unhelpful and sarcastic its really poor actually as it helps no one.
It's not that, it's that when you register, there are links the community asks you to read, which will usually give you the answers to the questions that many or most newcomers might have.
It's a courtesy to the community to do the research
before asking questions, to prevent the forum from being cluttered with the variations on the same post, dozens or hundreds of times a day. See the various Reddit replica forums if you don't mind that...just don't be surprised if the valuable information you seek is buried in thousands of posts asking "Who has the best AAAA+++ Super Rep Submariner?" and "I bought this rep for $100 on vacation in Thailand, is it good?" or even "Where do I buy a good Daytona?" etc, etc, etc. We try to keep this forum "clean" to avoid that issue.
Read the links in post #5, please. It's the least you can do to show courtesy and respect for the members here, who...believe it or not...have TONS of valuable information that they're usually happy to share, provided you meet them half way. What we don't want to have here, is a forum flooded with superflous and unneccessary posts asking the same thing...essentially "burying" the valuable information we come here seeking.
This is a community full of passionate enthusiasts, many of whom have spent years, thousands of dollars, and hours of sweat equity into solving the problems that most people come here with. Most are happy to share the information, although some indulge in a little "hazing" of the new guys, it's just how it is.
Picture going to a dinner party, where people with a common interest gather to discuss things of mutual interest. Now picture the conversation keeps getting interrupted by someone's kid asking the simplest questions, to the point where nothing can be discussed.
That said, welcome to the forum, I see you're NOT asking questions and in the welcome section, so don't be discouraged...just learn what you can, contribute when you can, and enjoy!
