Now you say the above. When did you change your mind? Simple: 1) It was clear to everyone that EH insertion wasn't allowed. 2) Some folks came with a funny interpretation, such that EHs could be inserted. 3) Lots of supporters of EH-insertion (mostly from the same company) argued that "it wasn't forbidden". And this wasted lots of people's time. So a clarification is warranted. That's it. P.S.: And then folks wonder why people "give up"?? Me, I'm not wasting more time on this. It should be pretty clear to the IESG what's going on here. Thanks, -- Fernando Gont SI6 Networks e-mail: fgont@xxxxxxxxxxxxxxx PGP Fingerprint: 6666 31C6 D484 63B2 8FB1 E3C4 AE25 0D55 1D4E 7492
