I've just started with my demo of v5.2 and have a few questions:
1. Can you limit the size of attachments, both in file size and dimensions (for pictures)?
2. Can you resize a picture once it has been added to a post?
3. If you paste a link to a Youtube video, the video appears embedded in you post. Can the same be done for links to websites so that a preview of the content is shown?
That's all for now, but I'm sure I'll have more questions as I work through the demo.
