hey bro, go and click on "post new thread" at the start of the forum. then scroll down and u will see the attachments section. u should see something called "manage attachments". click on it, there should be a pop-up. click on "add files". then click on select files, and then browse for your lobby song/sound. then click on upload files.
any more problems ask or pm me.
thank me if i helped u.
if there is a "X" or "!", means file too big.
