RE: categories
Hi Lynne,
Catergories are proably best used in Contacts, and best use is for people who deal with sales or mass mailing. When you create a contact and click on categories it gives you a selection of which you can create your own ones. Once you have choosen from the list or added new ones they get assigned to that contact but you can have as many as you want. Once you have done this you can then group people or groups by these catergories. When you are in the contacts section you will get different ways you can view them and if you choose By catergory it will do just that. The advantage is that you can then select the catergory name and click on the new message to contact button on the toolbar. This creates a message to all those users. It is a bit like creating distribution lists.

Martin
