I have been using nonumber extensions for about 4 years (off and on) already i think, and never had the need to call for support. Last week though there was a small peculiarity with sourcerer and support has been excellent and more important the small problem solved.
Brilliant extensions and top support, so i thought it would be more than fair to express my appreciation for giving these extensions for free for all to enjoy.
One thing i didn't like is the extra js being loaded for this component. That seems to be the norm with all ticket/helpdesk components, so that's more a general remark about this category than about this component.
For me the search continues for a lightweight reasonably feature rich helpdesk system, but considering all listed components this one is pretty smooth.
