The closest thing this group has to "rules" is the original charter,
written somewhere around October 1, 1992. It's more interesting as a
historical curiosity than as a useful set of rules, though.
I assume that some of the charter doesn't apply any more, now that the
RC folks have their own groups. But there's nothing in the charter one
way or the other about for-sale lists.
It's part of my job to know where to find a copy, so here you go - the
rest of this posting (except for my sigfile) is the group's charter, 11
years old last month. Enjoy...
The designated purpose of this group is to discuss the hobby of scale
modeling. Within this realm is included static (display) models,
radio-controlled models built to specific designs, railroad modeling,
model rocketry, and moany other aspects. However, the scope of this
group is restricted to construction techniques and issues, discussion of
materials and kits, discussion of local, national, and international
events, and other topics that pertain to the general hobby of
craftsmanship. This group is not a forum for discussion of controls
(radio or remote), for discussion of performance of RC engines, rocket
motors, or any other subject that, while part of a modeling-related
hobby, does not pertain to craft skills. This group is meant to, among
it's primary purposes, augment the existing rec.models.* groups by
providing a forum for the reader that is more directed towards "How do I
do this?" rather than "Brand X motors only deliver half the promised
power." While modeling is generally associated with plastic kits and
IPMS (the International Plastic Modeler's Society), this group will not
be affliated with IPMS, nor will it be limited to plastic modeling.
Most of the newsgroups charters are based around the original Usenet
Guidelines which can be found on the Net.
One idea is to put an indicator in capital letters enclosed in square
brackets, in the subject line. For instance, adverts (which are allowed
if relevant and not swamping the newsgroup) are usually indicated by
[ADV] "some text" in the subject line.
