Just occasionally, we have noticed a discontinuity in the pNBR numbers of the submissions that reach us. Thus we have failed to receive wanted and valued updates.
This has happened several times recently and we have inferred that it is just possible that the common factor is that the e-mail address of the submitter ends in @yahoo.com. So please, if your e-mail address ends with that character sequence, may we ask that (if possible) you use an alternative e-mail address, or that a colleague send the submission on your behalf. (No problems seem to occur when @yahoo.co.uk addresses are used.)
