All support questions for the Flickr Tag Cloud Widget plugin should be directed to the main WordPress.org Support Forum. The old support forum for this plugin with be going down this week.
Please be sure and remember to add the flickr-tag-cloud-widget tag to the topic when posting on the WordPress.org Support Forum.
This will be the only place that I will be helping out with issues related to this plugin. I hope you find this support forum as helpful as the old one.
