>For a simple test, if you go in Search and Calendar, can you select .Net framework forum or VFP Portuguese Edition forum for example. If yes, can you apply a search on it to see if that will work?

Search shows them fine as valid options. I searched in VFP Portuguese and it worked.

>If that works, in Time warp, from Dashboard, can you go back one day to see if you'll get all those messages? In order, they'll appear at the end of the list of messages as those forums were created recently.

Tiem Warp did not show anything in these forums (Portuguese, .Net, Chatter).
I do not get any of these, including chatter when I login. I only get VFP, Internet and Palm & Handheld.

When I press "Get all messages for today" I get Chatter, but not Portuguese or .Net

I have no idea why.
