Yes, Uncle_W, those letters are correct. And to you and Lumen both : those letters form the instruction buzzb refers to, also DJA in comment 27. DJA hints that one of the words in the 2,4,3,5 is also a word in the puzzle title. So now you should have the 2,4,3,5. It's a funny sounding instruction, you'd think the first word was redundant, but it fits with the puzzle title. Then execute the instruction. That involves a 10 letter anagram.
Rickye, you and me both, It's a solitary pursuit now. But conversations on this forum provide some compensation (aside from the occasional snooty visitor !) You're kind to suggest that I have brains. I don't really think so, in many spheres I'm slow to see a solution. There are others who contribute to this forum who are usually quicker than me...
