[eluser]Unknown[/eluser]
Hello fellow codeigniter users I just want to know if where can I download the latest revision of dx_auth/capcha plugins. I wanted to try it on the latest version of codeigniter 2.1.0 because i will be having a new project this coming month and it should have that kind of feature. thanks in advance for those who will respond.
