SYSTEM@V1.ESP.SOTON.AC.UK (03/12/88)
Hello out there,
I posted the following message several weeks ago, but did not
receive a copy of it back over the net, so I am sending it again, in the hope
of some replies. There seems to have been some problem with incoming info-vax
mail to the UK in the last few weeks - it stopped for a while (!), but I think
it's ok now.

Thanks in advance,
