>>1. where can i set the spelling language?

 
Open your web.config.

CustomCulture="fr-fr"

 

The Spell checker will use the same language as the editor.

>>2. can i set layout/ toolbar profiles for more groups than admin, reg. users guest.?

 

Yes.

 

For example, you have two new roles, "test" and "Content Managers".

You can put the following code into your web.config file.

 
     Test_AutoConfigure = "Simple"
     Test_SecurityPolicyFile = "default.config"
     Test_TemplateItemList = ""
     Test_DisableItemList = ""
     Test_AllowPasteHtml  ="true"
     Test_EditorOnPaste  = "default"
     Test_ReadOnly = "false"
     Test_ShowBottomBar ="true"
     Test_ShowHtmlMode  ="true"
     Test_ShowPreviewMode  ="true"
     Test_EnableStripScriptTags  ="false" 
     Test_EnableContextMenu    ="true"  
     Test_EnableContextMenuEditing  = "true"  
     Test_EnableContextMenuFormat   = "true"
     Test_EnableContextMenuInsert  = "true"
     Test_EnableContextMenuInsertAdvanced  = "true"
     Test_EnableContextMenuInsertFiles = "true"
     Test_EnableContextMenuInsertForms = "true"
     Test_EnableContextMenuRelative = "true"
     Test_EnableContextMenuTags = "true"
     Test_EnableContextMenuVerbs = "true"        

     Content_Managers_AutoConfigure = "Simple"
     Content_Managers_SecurityPolicyFile = "default.config"
     Content_Managers_TemplateItemList = ""
     Content_Managers_DisableItemList = ""
     Content_Managers_AllowPasteHtml  ="true"
     Content_Managers_EditorOnPaste  = "default"
     Content_Managers_ReadOnly = "false"
     Content_Managers_ShowBottomBar ="true"
     Content_Managers_ShowHtmlMode  ="true"
     Content_Managers_ShowPreviewMode  ="true"
     Content_Managers_EnableStripScriptTags  ="false" 
     Content_Managers_EnableContextMenu    ="true"  
     Content_Managers_EnableContextMenuEditing  = "true"  
     Content_Managers_EnableContextMenuFormat   = "true"
     Content_Managers_EnableContextMenuInsert  = "true"
     Content_Managers_EnableContextMenuInsertAdvanced  = "true"
     Content_Managers_EnableContextMenuInsertFiles = "true"
     Content_Managers_EnableContextMenuInsertForms = "true"
     Content_Managers_EnableContextMenuRelative = "true"
     Content_Managers_EnableContextMenuTags = "true"
     Content_Managers_EnableContextMenuVerbs = "true"   

Keep me posted.
