i have no idea how to get add-ons and i really want to know, if you tell you you will rock for ever!!!!!!!!!!!!!!
Download an add-on, and using WinRar or something else extract it to your main Blockland folder, not the add-ons folder. And for more complicated add-ons just read the topic or ReadMe if there is one.Also, read this: http://www.blockland.us/smf/index.php?topic=18304.0
