[ALUG] GPG key question

Hi All, I have a GPG key that I managed to get signed at a keysigning party at FOSDEM a few years ago. I want to create a new key, but that obviously will only be self signed. What would you suggest as the best way to proceed with a new key? Does anyone know of any keysigning parties locally (e.g. Ipswich or Norwich). Or failing that, is signing the new key with the old key and vice versa the best way to plug it into the web of trust? Cheers, Ewan
