Changeset 27257 for main/trunk/greenstone2/macros/document.dm

Timestamp:

Message:

Add User Comment form. Allows adding username, timestamp and comment to a document. Need to still display the just-added comment when the ajax reloads the page. Also should not display the form on a non-doc page, like when browsing a classifier.
