Welcome, here's my experience:
I started in MRR toward the end of last year. I stopped at several forums and posted some newbie-type questions. I got cordial and informative replies on a few forums, but on the Atlas N scale, all I got were a lot of viewpoints, and why I should conform to theirs. No real answers, no substance, and it took a lot of effort to wade through the ton of posts. I didn't go on one day and my thread was on page 4, I missed a week and my thread was now on page 18. I went back a month later to post an answer to my questions since no one else did, and I had to dig my thread out of the archives. And I couldn't believe the all-knowing responses other people got to their innocent posts.
This forum goes at a nice pace, and I have yet to have anyone appear agumentitive and anything less than helpful. I visit a few forums now and then, but I feel accepted here, and besides, who has all that time to visit and post all over the internet when they can meet all the people and get all the answers they want right here?
