This is a strange one, and I'm wondering if others are experiencing the same thing.
When I'm accessing new posts, topics etc. in "Cameras, Lenses and Shooting Gear", "Digital Image Processing", "Digital Cameras, Backs and Shooting Techniques" etc., the forum is extremely slow in responding to a click on the link for tracking, on replying to new posts, previewing, etc.
Edit: posting this new topic was also dead slow, but tracking it and hitting the "edit" button was quick.
I would guess that the site is being hammered due to the review of the new Adobe beta software "Lightroom".
A number of other sites are pointing to the review by Michael. Including DPReview, and others.
