After recent messages, I've banned nabble.com from posting to the list. The signal to noise ratio was just too high. The overwhelming majority of the questions were... not good. I've discussed this off-line with the nabble administrators. The nabble pages are now marked read-only. i.e. you can read the list there, but you can't post using nabble. As always, *good* questions get *good* answers. This list is here to help people, and it does. Alan DeKok.
