Give detailed information about your setup, tell the version of kernel, dosemu etc and name the observed errors. You can use xdos to cut and paste the error message into your report. But keep your report in a readable form. So only send the active lines from your dosemu.conf. Try running dosemu with some or all debug output turned on and scan through your debug output and at first only send those parts you think are relevant.
Few people are willing to decode some long attachment to a mail, to do debugging for others.
But keep your logs at hand, in case others ask detailed questions. If you do not know SGML, that's ok. Changes or new information in any form will be accepted. In short, we wish to promote dissemination of this information through as many channels as possible.
