Please could someone point me towards the idiot's guide to MN: I can't read profiles; I can't find threads I've posted on (can one tell if they have been deleted?); I can't find out if the thread I'm looking at is a duplicate of one by the same person from the previous week. I know that some people allude to poster's previous threads so there must be a way to find them but I don't seem to be able to work any of this out for myself!
Thanks in advance.
