Ben, 60 and 72, i guessed.
for 13 i was quite surprised that http://crossword-solver.utsire.com/
solved this one(might well do the other 2 - i tried the 1st one with no luck).
ps. this is what i entered
?i???e,??u???,??ou??
ie,commas between words.
Thanks Trevor for that site info, have been on and had a play around, this may help me with various questions without having to bother always looking for help.
Would agree with Ben that Trevor has given a good site have just found 10 of my outstanding dozen on this one but had no success with these any help appreciated
