The group is a category or client you want to group a list of projects by. For example, "Programming" or "Goober, Goober & Dumpling." The project field is for the project name itself, such as "Testing" or "Meeting." Time is for the time elapsed on the project - which defaults to zero. The billable checkbox determines if the project is billable or not... i.e. "Lunch" would be non-billable, but "Write Code" would be billable.
To edit a project, just double-click it. To delete it, either right- click on the project and select "Delete," highlight and hit the Delete key or highlight and select Project->Delete Project. To start the timer for a project, highlight the project to watch and hit the "Start" button. Hit "Stop" to, well, stop.
To edit preferences, go to Tools->Preferences. The first tab to open is General Properties. Here you can have time elapsed shown in minutes or seconds. You can also specify how often prefs and times are saved to your user directory. Animated icons used in ConsultComm (such as the rotating bar at the bottom of the window) can be turned on and off in the animated icons checkbox.
The next tab allows you to specify skins to change the look and feel of ConsultComm. Skinpacks can be downloaded for SkinLF at http://javootoo.l2fprod.com/plaf/skinlf/index.php - just specify the skinpack at the "Use Theme Pack" field.
