Hey Jim, no ND filter. It's all about timing. I prefer to shoot my moon shots while the sun is still up or just setting so that the ambient light around the moon is not that much different then the brightness of the moon. It makes it an easy exposure with no fuss or muss.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
