The forum is still too slow to be usable at times. Just about half an hour ago, I repeatedly got time-outs, so I could neither read nor post.
When posting, I sometimes cannot post because the forum does not react at all. At other times, there is a reaction, but it’s just a simple error message telling me that something went very wrong and that no information is available.
Most common, though, is a message telling me that I did not enter the text of the security image correctly – even if I’m sure I did. This then happens repeatedly. Sometimes the system shows the same security image again, sometimes a different one.
I find I have the highest chance to succeed at posting when you get a new security image, then enter the text of the previous security image.
Technically, it may have something to do with the wrong image being shown because the browser uses an old image that is still cached somewhere. A forum (and HTML) expert might be able to tweak the HTML headers such that the security image is never cached.
