I am using Joomla 2.5 as a CMS for our project website. I would like to ask users to select ONE unique choice from a predefined set of elements (more specifically: select one country from the list of countries) so that the selected element is not available / highlighted for other users in the future, I assume that I will need some kind of database in A background mode that keeps track of available items and saves items that have already been selected. Besides the standard Joomla 2.5, I have access to RSforms pro, but it does not seem to do the job. Any suggestions?
