Somehow this forum doesn't use your login by default, but a profile name made from your surname and last name. You need to go to your profile to change your displayed user ID on the forum. Could the other user be your MySupport account? Those got transferred automatically to the Intel support (with a password reset) and now both the Mysupport and the forum accounts are on the same platform. I had a problem with that because both accounts use the same email address.
From what I understood Intel is working on the performance issues, and will get the Google search working again. The links to the old posts in Altera forums should also be redirected automatically to here.
I've talked about the read/unread marks, and having a list of all the unread messages since the last log in, which in my opinion are the basic minimum functions that are required to make this forum usable. We'll see where it goes from here
