My user is arriba, not rgdesign. I notice this when i did my last commit. I can´t edit the author, and in his user page, my plugin looks like yours. But as you can see clicking on Donte to this plugin, that takes to my website.
I´ve noticed i put under readme.txt file, wrong me, Contributors: rgdesign, spite Contributors: arriba. So, i´ve change all those things over the current svn version and on all tags, just v0.1 and v0.2. I´ve changed the Contributors, to my user ID.
But nothing, steel apprears the logo and user id/link to other user, not me.
