Introduction:
Organization governance can allow the end users to add the terms to the term 
store. In the term set settings there is an option called "Submission policy" 
which is used to allow the end users to add the terms to the term set. The end 
users can add the terms to the term sets in the metadata column dialog box. In 
this article we will be seeing how to enable this option to add the terms to the 
term set by the end user using SharePoint object model and powershell. In part 1 
I have explained how to set the submission policy through UI.
Using SharePoint object model:
Steps Involved: 
Using powershell:
Steps involved: 
- Go to Start => All Programs => Microsoft 
	SharePoint 2010 products => SharePoint 2010 Management Shell.

 $taxonomySession=Get-SPTaxonomySession -Site "http://servername:10/"
 $termStore=$taxonomySession.TermStores["MMS"] $group=$termStore.Groups["Submission 
	Policy Test"] $termSet=$group.TermSets["Days of the week"]
 $termSet.IsOpenForTermCreation=$true
 $termStore.CommitAll()
