I'm a noob to Vanilla and a noob to web development so please bear with me. I've hit a snag with installation. I've downloaded the open source software, loaded Wordpress and installed the Vanilla Forum plugin. The settings say you have to set up a forum and there is a button to press to do this. This takes me to their plans which are expensive. I don't know how to do it for free. There is an open source to download but I don't know how to install that. Please help.
