Popis Logging and Bookkeeping (L&B) is a gLite subsystem responsible for tracking jobs on the grid. Normally the user interacts with it via glite-wms-job-status and glite-wms-job-logging-info gLite commands. Here we present other, less generally known but still useful L&B usage patterns which are available with recently developed L&B features. L&B exposes simple HTML (for humans) and plain text (for scripting) interfaces over HTTPS. Hence, for example, pointing a web browser to a jobid yields human-readable page on the job status details. Similarly, the plain L&B server endpoint URL shows a clickable list of an active user's jobs and notification handles. Apart of actively querying L&B server, users can also subscribe for receiving notifications on job state changes. Possible criteria range from simple "whatever happens to this job" to "a job of this VO user gets resubmitted to another CE." We demonstrate how to use notifications via both API and CLI.
