Thanks for these tips. The site is fairly intuitive and I was able to figure out most of this by myself. I've often struggled with the right things to use as "tags". I'm skipping tags for now...but if you have any advice in that arena, I'd love to read about it.
Yeah, it's pretty straightforward. Just trying to catch people on some of the photo posting things before they post too many - and then feel like they should re-categorize. As for tags, I think going with the recommended ones, or merging recommended ones is a good bet. Or using what you think would be common search terms related to your post. These tags are used to pull up content in web-based searches.
