I am able to post now (this message) for the first time since 3/29 Saturday. What I experienced was the forum pages were available if you accessed the page as a guest (no registration), so you could browse...but as soon as you signed in to show your member id, the pages would no longer load. It would display a blank page for any Obi forum URL, and obviously you could not post any new messages.
If you logged out and reloaded the page, you could again browse the old posts, but still could not log in to reply.
Was this the case for everyone else? I noticed a few people were posting the last 2 days, but it traffic seemed to be much less than usual. And how did you people get in (those who were able)? Was it just me?
