[MidLifeXis]: Project Admin, a while ago: "No, I would prefer you didn't close that ticket yet confirming $vendor's support process yet. Continue to periodically check back to see if it has changed."...
[MidLifeXis]: Project Admin, today, after many periodic updates from me: "Why hasn't this been closed yet? Is there anything I can do to get this closed?" <facepalm>
[MidLifeXis]: In addition to SOAP (last hour of cb), try water. ;-)
