To upload a replay:

1) Click on "Go Advanced" under your post.
2) Click on the paperclip on top of the text box, but under the title box. If you can't find the paperclip, just scroll down under your post until you see "Manage Attachments". Click on that.
3) (A new window should have opened up allowing you to upload various files to your post, in your case, replays.) Click on "Browse", and select the replay you want to upload (you can upload 5 at a time). When you're done selecting your replays, simply press the "Upload" button, and you're done. The default location for your TB replays are: My Computer > Local Disk > Games > Toribash > Replays.
