Mainly the rule relevant Groups on Facebook I suspect or the new Lard Forum which replaced the version lost in the great website crash. Though the latter is less busy these days.?
I've always preferred/turned to the forum for questions/discussions...probably because I never used (and developed proficiency with) the 'scrolling format' of chat-type-sites that are difficult (for me) to navigate and whose annoying algorithm tells me what I'm interested in...
