The plugin provides some information on the left hand side when you configure the plugin, and the tooltips should provide you with a lot of information about each single option.
Apart from that, you can contact me trough the forum (click support above), but you may also email me directly (my email address can be found in the Extension Manager, tab Manage: hover over my name in the row where read less text is listed).
Hope this helps a bit,
One more time, where is my ReReplacer for J16?. Please hurry!!!
