Dear Fred,

there is a Bruker mailing list (bruker-...@g-groups.wisc.edu), that
acts as a ccp4bb for small molecule crystallography.
As far as I know, there is no automatic inscription, and you should
write to Ilia Guzei <igu...@chem.wisc.edu>

It is good you are on linux, that's one thing less to worry about.
If you want to use SHELXL with Olex2, you need to add SHELXL to your
PATH environment, either in a terminal from which you start Olex2, or
into the 'start' script for Olex2. In SHELXLE, you can add the SHELXL
command from the last menu item in the menu 'SHELX'

SHELXL typically writes these types of error into the lst-file,
underneath the line in question. If you copy the line, you most likely
will get a quick answer. It probably refers to a line that starts with
4 characters which are neither a recognised SHELXL command
(http://shelx.uni-goettingen.de/shelxl_html.php) nor a qualified atom
line.

Best,
Tim
