There is now an amendment to the sig rules, as I have just spoken to Nick.
Reciprocal links back to Oprano although a very cool gesture on your part, will no longer be enforced so vigorously. Which means everyone is now allowed to display:
Sig buttons at 120x60 with 3 lines of unaltered text .. maximum!! unless you are a sponsor of Oprano, in which case you can run banners
.
