Helpdesk helpdesk@stat.rice.edu is a place where you can ask ``How can I...'' as opposed to the ``What's wrong with...'' question you send to the Rice problem tracking system. Helpdesk also maintains a list of frequently asked questions, some how-to files and some sample dot files. The present helpdesk consultant is Bo Peng bpeng@rice.edu.
Although helpdesk and problem tracking system have different functions, you do not have to think hard where you should direct your problem to. You can submit your problem and add helpdesk@stat.rice.edu (and some times Diane mailto:dbrown@rice.edu) as an interested party, and helpdesk will reply your question if appropriate. Questions that should be send to problem tracking system will be forwarded to it if necessary.
