Good afternoon. My name is Leandro and I am using MediaWiki for the first time. The instalation was very peaceful and successful. I am encountering problems in the administration of users x groups of the system. Using the option Special: Userrights I managed to create new groups. There are some extensions to facilitate the display/administration? It is possible to have support in Portuguese? If some using Brazil level will be able to help to mine msn is: lsouza_rj(a)hotmail.com thanks Leandro Souza
