We resolved an issue with the site not sending updates when Answers were provided. This fix had a side-effect of going back to old posts and triggering email. Sorry for this but it was a one-time event we didn't see in other environments.

Ok, you're right about the font not looking correct in "My Content". This build didn't intentionally change anything here and I have to admit that it's an area of the site that hasn't been given much attention.

So that begs the question - for both "My Collaborations" and "My Content", what information should be displayed? My Collaborations currently shows what looks like the complete posting, while My Content shows something different.

What is the appropriate level of detail to be showing here?

No, I think this was a one-off when I replied anonymously on my phone. Comments are not being displayed like this.
