I've managed to succesfully create a document in a "settings" folder when a user makes and online enquiry to allow the client to view all enquiries.

Once thing i've notived that the name of the document just gets another (1), (2) etc on it...is there a better way to handle this?

Also I have no need to publish these files...is there a document type that i should create/use when storing data?

Code below..

'Now lets update umbraco so the client can view the enquiries
        Try

            'Get the type you would like to use by its alias
            'and the user who should be the creator of the document
            Dim dt As DocumentType = DocumentType.GetByAlias("tmGetInTouchResponse")
            Dim author As User = User.GetUser(0)

            'create a document with a name, a type, an umbraco user, and the ID of the document's parent page.
            'To create a document at the root of umbraco, use the id -1

            Dim doc As Document = Document.MakeNew("Response", dt, author, 1480)
            'Now enter the stuff we need to capture
            ' the value is saved in the database instantly!
            doc.getProperty("name").Value = txtFirstname.Text & " " & txtSurname.Text
            doc.getProperty("enquiryDate").Value = DateTime.Now
            doc.getProperty("contactTel").Value = txtTel.Text
            doc.getProperty("emailAddress").Value = txtEmail.Text
            doc.getProperty("enquiryDetails").Value = txtDetails.Text
            doc.getProperty("newslettersignup").Value = Newsletter

            'after creating the document, prepare it for publishing

            doc.Publish(author)

            'Tell umbraco to publish the document
            umbraco.library.UpdateDocumentCache(doc.Id)
        Catch ex As Exception

            panFeedbackSucess.Visible = False
            panFeedback.Visible = False
            litInfoErrorMessage.Text = "<p>Sorry there was an error we did not manage to capture your details to the database but they may have been sent by email.</p>"


        End Try
