Hey Wikimaniacs,
If you're like me, you may find it a bit cumbersome to add yourself to the list of "Interested attendees" on Submissions pages. It only takes a few clicks and keystrokes, but multiply that by the number of sessions you're interested in and *poof* your afternoon is gone.
Because I care about your afternoons (and about mine!), I've written a user script this morning that lets you do it in one click. If you'd like to use it, go to https://wikimania2015.wikimedia.org/wiki/Special:MyPage/common.js and add:
importScript('User:Guillom/addme.js');
The script seems to mostly do what it's supposed to do, but I'm still new to JavaScript so if you notice something wrong, let me know on my talk page. More experienced JavaScript authors are also welcome to review and improve the script and/or turn it into a gadget so that all users can use it.
HTH,
