Woohoo! del.icio.us links are back up and running thanks to the scripts author Brett. It turned out there had been some changes on the del.icio.us (Jeeezus, typing that is getting te.dio.us) site, but once fixed he was good enough to mail me with the adjusted code. Thanks Brett!
p.s – sorry for bugging you for help Sparkes, it wasn’t my fault after all
