I hooked up my card reader and had no trouble importing my recent photos into Lightroom. They went exactly where I wanted them to go on my EHD, too. Score! The next step is to scan through and delete the duds, then put keepers into collections. If I put photos into collections first, it is much harder to delete duds.
I did not sweat the naming of the directories on the EHD. I renamed the photos as I imported them and I'll be picky about naming the collections. This may change, as my ability to share photos might require it. I'm still blurry on exporting photos from Lightroom. I've only learned how to import and edit inside Lightroom so far.
