ISSUE:
On Internet Explorer, when subscribing to a User's activities, the corresponding page displays the Subject Name of "Untitled" . [Cosmetic issue, but needs to project Users' name or other pertinent info other than "Untitled". Screenshot Enclosed.

TO REPRODUCE:
a) Go to a Member's Personal Public Page
b) Click on "Subscribe to User's Activities" via RSS
c) IE will open.

Expected Result: The name of the RSS pertaining to the member should appear
Actual Result: RSS link appears, shows "Untitled" as subject name.

Compare this with the RSS feed link for the blogs portlet and you will see the user name as the title/subject.

NOTES: Only seen in Internet Explorer. No titles shown in Firefox or Chrome
