<P> You'll notice the download progress is visualized in the left bottom of the QGIS main window. Once the layer is loaded, you can identify and select a province or two and view the attribute table.
<P> Remember this plugin works best with UMN MapServer WFS servers. It still could be, that you might experience random behavior and crashes. You can look forward to improvements in a future version of the plugin.
<P> This means that only WFS 1.0.0 is supported. At this point there have not been many test against over WFS versions implemented in other WFS-servers. If you encounter problems with any other WFS-server, please do not hesitate to contacting the development team. Please refer to Section #label_helpsupport for further information about the mailinglists.
