The seasip.demon.co.uk pages will be shut down on 1 June. You should update your bookmarks to use seasip.info; if you were linked here from another site, please notify the owner of that site.
This move has been made necessary by the (deliberate?) incompetence of Vodafone, who appear to be trying to drive Demon customers away.
