The Meeting Manager Interface in Adobe Connect 6.2 has become Adobe Connect Central in V.7 -- and some of the functionality has changed. Hosts can no longer access the page to edit meeting information and participants directly through the Connect Central Web interface, but they can still get access to edit the meeting information by selecting "Manage Meeting Information" in the Meeting menu within a meeting room.
PRESENTERS are no longer able to edit meeting room information or the Participant List (even though the Adobe documentation says they can). You have to be a Meeting Creator or meeting Host listed on the Participant List in order to have access to the "Manage Meeting Information" option in the Meeting menu.
Complete directions (with pictures!) are located at http://meeting.psu.edu/editparticipants (directions for editing participants) and at http://meeting.psu.edu/editmeetings (directions for editing meeting information and settings).
