However scary HLP might be, stardestroyer.net might be the least newbie-friendly forum ever. It makes Something Awful look gentle and unintimidating by comparison. It's so scary I've lurked there for six years and never posted.
I think SDN's cooled off somewhat in recent years. It's not the forum it used to be, though the News&Politics section is still a flamepit. If you're not a complete dick or a complete idiot, and you don't break the rules, you won't get mocked (much).
How the hell HLP got considered less newbie friendly than SDN, though, I admit I'll never understand.
this has been a few years ago you realise

i havent been really active on SB for at least 2-3 years now.
oh but the riots that used to be there in the SB vs debates subforums....
HLP has arguably been in a bit of a worse state a few years ago then it is now. an0n and the ilk are the first that come to mind.
Also, mind you, there hasnt been the level of helpfulness and civility in FSO support back then. JeffVader and The E werent yet fully active there that way if memory serves.
