Re: Tags not separating
When the post is created, the tags are split on spaces, so foo and bar would have been created as separate tags. When you add tags to an existing topic, you can use spaces and enter tags one at a time. So you would enter foo and get a foo tag, and then bar and get a bar tag. My guess is that ‘foo bar’ was entered as a tag on an existing topic, and that’s how it stayed. If they were expecting the tag to be split on the space (like a new topic handles the tags) they would be surprised maybe to learn it works differently with existing topics.
