Attached is an enhanced version of the WeblogPlugin.java. It adds a "preview" parameter that takes an integer value after how many characters the entry should be cut off on the overview page. It then adds a "More" link to the full entry. If the parameter is missing, no truncation is done, as it is now.
Also needed is this in PluginResources.properties:
and this in PluginResources_de.properties
This addresses one of the questions asked on https://jspwiki-wiki.apache.org/Wiki.jsp?page=WeblogPlugin
