[Rhodes22-list] Web Interface: Searching the Archives

[Graham Stewart]

Peter:
The Rhodes22.net web page works beautifully for me. I have never really
been able to use the old system so this is a massive improvement. We are
very lucky to have someone with your skill and generosity of spirit to sort
this stuff out for us. Thanks so much!
