I haven't been around CC for quite a while but I have noticed a few quality posters around who I try and read when I get the chance. Slow Love (TM but can't be bothered and Neil, no I don't want to know how to do it
) always seems to know his stuff along with few of the 'older' folk who've already been mentioned
I'm also impressed with the people who can manage to not overkill their point of view, they keep it fresh, concise and helpfully insightful.
The forum isn't short of a few knowledgeable folk so I'll gracefully bow out of CC on that note.
