Installation and Screenshots won’t show up

Hi all,

I’ve managed to add my first plug in into WordPress. However, I couldn’t seem to make the “installation” and “screenshots” tabs show up.

Here is my plugin: https://www.ads-software.com/extend/plugins/digg-this-o-mine/admin/

And here is the repository: https://svn.wp-plugins.org/digg-this-o-mine/

I have followed the guide and had the readme.txt validated. Could anyone show me why?

Many thanks in advance!
