You sound like a nice guy.
Forums are funny things - you can have a long series of communication with someone without ever getting any clues about inflection and tone other than what you instinctively may perceive.
In others words, don't assume people are being either welcoming or unwelcoming. Many people write different than they talk and both emotion and tone are very hard to convey in writing (unless you are an expressive and talented writer).
There are a lot of warm-seeming people here who offer really crappy advice.
And there are a lot of crass and terse people that will bend over backwards to help someone out if asked.
