When I define a Workflow rule that a task should automatically be created for Cases that match specific criteria, the Task that is created is not linked to the Contact.  (e.g. if I click Edit on the Task, I can see that the Contact field is blank.)  The Case for which the Task is being automatically created, does have the Contract Name properly populated.  Is there any way to have the Contact information passed from the Case to the Task?

When I try to create a custom object called "Payment" I get the following error :

Error: The custom object name you specified matches a Salesforce name. You must specify a unique name

However, I cannot find this "Payment" object

1) In the help pages  on the site
2) In any of the Data Model diagrams in the API documentation
3) In the list of API Objects in the API documentation

Where is this object?

I would like to define multiple different layouts for the Case page layout based on the Type field.

E.g. If the Type = "Lost Password" I would like to show/hide/require different fields on the Case page layout then if the Type = "Item Not Received".

Is this possible?
