Please send an e-mail to a member of the SupportContactList, and we'll set you right up.
Please let us know how you'd like your Wiki secured. Should it be public (anyone can see, authenticate to write), or protected? Is this something that you would like restricted only to your unit/department? You can always fine tune access yourself -- see WebLoginACL.
Will you have collaborators from out BU who need to access the wiki?
We look forward to having you on board! -- members of SupportContactList.
