The SDD Wiki has moved to the TDWG Twiki platform http://wiki.tdwg.org/twiki/bin/view/SDD/WebHome If you don't care, you can stop reading now.
For a number of technical reasons, time constraints, and privacy issues, it is difficult to move wiki presences from one organization to another, so if you are a registered user at the old umb wiki but not already at the tdwg wiki platform, you need to re-register. Note however that I \have/ copied the email notification list to the new wiki, and if you merely register with the same wiki name, notification will resume. You can check out http://wiki.tdwg.org/twiki/bin/view/SDD/WebNotify. If your name appears there with a "?" it means that there is not presently a registration for you at the tdwg wiki. If you choose a different wiki name than you had at umb, you will need to edit that page if you want mail notification.
