I am glad to see this post as I had wondered if it was my computer. When I click "send" as in this post, it will take a long, long time to load and then still does not go through. I have to click "send" the second time before it posts to the board. And, PM's are way, way slow to upload and usually have to hit "send" the second time on those too.
All this has caused me to stay off the board more and get more work done otherwise.
