## Frequently Asked Questions
### What's the different between the "Subscriber" and the "Joomla User" plugin?
The information you can add are different, one come from the Joomla User table, the others come from the AcyMailing User table.
All Joomla users will have an AcyMailing account but if you handle visitors on AcyMailing, they don't have a Joomla account and so adding tags from the "Joomla User" table won't display any result in that case.
If you want to add the name of the user, please always use the "Subscriber" information, not the "Joomla User" ones to be sure that all your subscribers will have a name.
