?

@bharath:
Get most of the above questions answered via "g.version -br". Maybe the
"g.version" module could be enhanced to _also_ return the operating system?
As a side-note:
new user's ask naturally for support and very frequently the same questions
(like above) are asked from experienced user's to better nail down a potential
problem. Maybe we could use a wiki-page with standard steps like:
1. provide information about grass version, build, etc (use "g.version -br"
for example)
2. for raster related processing, provide the region size ("g.region -p")
3. etc.

I would second this Nikos - perhaps such instructions could also be emailed as a welcome note when a new user joins the discussion group? As a noob it is sometimes difficult to know what information to include in requests for help (and also how to get this info out of GRASS)
cheers!

And I second that ;-).
I don't know why I did not write that while I was thinking it, i.e. I was
thinking the welcome message and the list's netiquette. I thought it is better
to expect some first replies, then expand the discussion.
