Issues/Decisions

#	Issue/Decision	Notes

2	Do we need a second appender for errors?	one file only Later we will have a file to trackwho is accessing it, who is registering for the access...but we are not at that point yet
3	Is the file location ok?	../log/${logName}.log
4	Disk space	<property name="maxFileSize" value="20MB" />
