The best flash modifier I have found through the years cost me $5 brand new at a camera swapmeet. I am on the road and don’t have it with me, or I would send a photo of it.
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.
