Display module in which users can add informations without approval in the administration area. (News appear automatically when they are added).
If some user would like to highlight his entry, via an SMS he will have the possibility to: bold, and highligh his article.
Principle: sms send on number generated in dotpay -> return code -> user enter the code -> article is automatically bolded/highlited.
Script is available to download in the dotpay ww is, so it probably need to be implemented into Joomla.
