Druh6sm, Norah posted the Posting Guidelines recently, and in there it is suggested that 3 questions at a time are probably best. More than that it can get a bit unwieldy - if different people answer 1,3 and 5, somebody helps with 1,2, 4 and 5 and so on, other solvers lose track of what's going on! Solvers can return with another batch. I don't think there's a limit on the number of batches - my view is that if you need help with half the clues, it's turning into a shopping list!
