Fair point. Though I feel the hierarchy rules are less strict in alt.* -
you don't have to convince the news.groups regulars that your group sits
correctly in the big-8.
I don't follow Chris' point about not creating extra hierarchies: I think
that's more to prevent levels being set up which are unlikely to have other
members - ie alt.sport.bunny-hopping rather than alt.sport.bunny.hopping
(because short of alt.sport.bunny.eating, there aren't going to be any
other likely alt.sport.bunny.* groups). So creating an alt.*.riscos.*
hierarchy is OK, as other groups might follow.
Silly suggestion... how about alt.comp.os.riscos.neighbourhood, or
a.c.o.r.n...? :) <ducks>
Anyway, here's a first stab at a charter, with footnotes where work is
required. Insert your favoured newsgroup name as you wish...
REQUEST FOR DISCUSSION
For your newsgroups file:
alt.comp.os.riscos.community Misc chat between users of RISC OS
Discussion about the RISC OS operating system forms the vast majority of
traffic in the comp.sys.acorn.* hierarchy. This operating system has a
loyal, close-knit community of users who often know each other socially
and would like a newsgroup to discuss matters not directly relating to
RISC OS systems, which are off-topic in comp.sys.acorn.*
Currently such traffic is carried in the argonet.zfc newsgroup, limited to
one ISP (average XX posts per week), the archive-42@somewhere mailing list
(XX posts/week), and off-topic posts in comp.sys.acorn.* (XX posts/week) 
alt.comp.os.riscos.community is for discussion of matters of interest to
users of the RISC OS operating system that are not strictly involve RISC
OS. Nothing is specifically off-topic but posters are required to have a
current or former connection with RISC OS, either as a user, developer
The group is unmoderated. Posting binary attachments (with the exception
of cryptographic signatures) or messages in HTML is forbidden, whilst
top-posting is strongly discouraged. Commercial adverti *** ts are not
Places where some help would be useful:
 This needs to be short and snappy (my 'tin' shows the first 29 chars).
Can anyone do better?
 I don't have access to these: can someone provide some statistics?
 I was getting into difficulty here: how do we define the charter to
cover things that are essentially undefined? Do we want to exclude
discussion of RISC OS? (I suggest not, as that might make the group name
harder to justify)
 It's usual to say 'posting of on-topic commercial adverti *** ts is
allowed once per 30 days'. But here we don't have anything that's
off-topic, so such a clause would mean all infrequent spam was acceptable.
 Anything else I've forgotten?
