That's not the point, and besides the dxForums and other links on top are still available and seem just as forum related as the ones that disappear . Why replace these useful links with empty black? I know that is probably a ZenFro thing.
BTW, they disappear when you are looking at a forum view as well (or subforum). Also, if I click one of the forums, like the general discussion forum, the anchor is moved under the top nav banner, so you can't see the first forum in the list.
I know how to fix that too, scroll up (or down).
I'm sure these nuances just need feed back to ZenFro and hope they fix it.
I think where we are now, the forum seems up and running, so the only thing left is the core design.
