Hi Paul, yes it is a bit of a commitment, but I think it's worth it. I upload my shots everyday to facebook, Flickr and onto here, but they are all on my pc and back up drives as both RAW files, print sized files and web sized files.
I suppose if you miss a day you can carry on, but it's not something I've done yet & with only a month & a half left, I'm determined not to do it.
