So I've decided to start uploading, but I can't really do that when after writing out the various tags and a description, I wait for about a minute after clicking the upload button to find that no, my work hasn't been posted, and the time I spent arranging for it to be posted has been wasted. Has anyone else had any problems with this?

Are you uploading from a direct URL or from your PC?

I've been trying to upload from my PC.

I sometimes have trouble uploading files through chrome, but using a different browser like firefox tends to work for me.
