If you're using a decent forum, there should be a way to upload directly via the forum. If not, you can either do what jeff said, or you can use an FTP client to upload it to your site and link to it that way. As for the chmod question, the last argument is the file you want to chmod. It can be either a relative or absolute path. If ou want to do it to the current folder, just put a '.' (dot).
