I'm still starting to use GRASS, and I have to admit that I did not very much
yet. But I want to go so... so I have some questions:
With our students we want to transfer geomorphologicla maps gained in the
field into GIS. Is there a symbology for this in GRASS, has someone built
one? Can I build my own symbols?
Thanks to all!

1.a) symbols in display monitors
d.vect and d.graph will let you represent point data with display
symbols. (custom scale or color based on an attribute column is allowed,
moslty in GRASS 6.1-cvs version)
built-in symbols:
basic/:
arrow2 circle cross2 marker point star x
arrow1 box cross1 diamond octagon pushpin triangle
Much the same as for d.vect, d.graph you can use point symbols.
Also in ps.map you can use Encapsulated PostScript (.eps) for symbols.
I hope that someone will one day write some conversion code to translate
.eps to d.graph commands so d.graph can display .eps too.
2.a) area filling in display monitors
You can pick a random color based on category or custom color based on
an attribute column. For raster maps use r.colors to set colors.
I don't think hatching is done easily? (nothing's impossible...)

I would very much like to see some common patterns added onto the Wiki
page like we have for the custom symbols repository above.

2.c) load the map in QGIS and edit the area fill properties by double
clicking the map's color box in the layer list on the left. http://www.qgis.org
You need the GDAL GRASS-plugin installed for QGIS to be able to read
GRASS maps.

I've added a wiki page for these, linked from the add-on's page
