I would like to know whether, and if so, under exactly what possible circumstances, an Area 51 group can be completely deleted.
Also, I have seen several groups being closed, and it doesn't seem possible to normally browse the questions of closed groups. I find this a bit of a disadvantage, since, even if the group is not very active, the information it may contain may still prove useful to someone.
For instance, yesterday I found an Accounting closed group, but couldn't browse the questions. Today that group seems to be gone (and replaced with a new Accounting group which currently only seems to have 3 members).
If I could have browsed the old group, I could have at least been able to use SE to become familiar with the vocabulary of accounting even if many of the questions hadn't been answered, so it would have been still useful this way.
