Drop-a-Note is a self-supporting Short Messaging module that allows your website visitors to post messages without having to register first. No 3rd party subscriptions, keys or APIs are required.
Messages are displayed in a scrolling window. Unregistered visitors can published through an emailed activation link. Registered users can post without delay, i.e. without the need to activate.
The limited trial edition will give a feel for what the 'real' module can do. The full features are available in the Premium Edition which can be downloaded from the project website. Also available for J15.
