Collectible Card Game Headquarters

Hello! I'm new and I'm trying to upload a file to a post but it just keeps loading without posting. Do I have to be a member for a certain amount of time before I can post something with an attachment or a link to an outside page?

I have created substitute sound files for the Microprose version of Magic the Gathering to replace the very loud dual sounds with ones that are roughly half volume.

You need at least 5 posts to be able to attach files.

Thank you!
