Could be a good module, but it needs documentation or forum for sure!
This plugin is too simple for having a forum with only one thread saying: "you must activate it after installation."
We should note, that being a content plugin, you must have some content to display, for showing the disclaimer. In Joomla that must be an article.
I've been testing my contact form with several web browsers and works ok, so, update your browser or something...
Negative reviews do not help to improve the plugin if they say nothinig constructive.
Anyway, if you tell me what kind of issues are having with the plugin, I will be glad to help you.
