The DeveloperWorks help desk folks worked yesterday to diagnose the issue where many of you cannot post a reply. This is the information I received last night:
"It was people coming in through an RSS/Atom link. We have extra tagging on the link in that case, "&ca=blah", and that was corrupting the XML that we use in an AJAX call in Roller to personalize the page. We are working to fix this."
Thanks for your patience with this. This is part of a big "Collaborating with Customers" release of Notes, and to me, this blog and the responses to it have become mission-critical tools. I do not know if any other blogger at IBM is using their blogs in this fashion, but the support people are VERY aware about the volume of hits that this site gets.
