The time limit is quite normal on forums. Although it is possible to edit posts if you spot a typo or similar soon after the post being made, it is not fair to be able to edit a post after someone has replied, as you could go back and completely change the post to say something different.

I don't have VV1 on this machine, but ISTR that the sort order in the details screen was by age, not name. In VV2 you have three options, to sort by age, experience, or health.
