It's probably about time I did this, so last night I rewrote the love map code. Partially to fix some stupid issues - like having to type your name in exactly in the right case. Sure Bob ain't the same as bob, but there's no reason why I can't do a case insensitive search on what names are in the system and find the one you used.
But mostly cos the code was so goddamn ugly :D (although hopefully not so horrific as to be likened to goatse as blue_cat mentioned previously o_O)
I've also started to include future provisions for being able to change your password - it's just a case of replacing the old private key with the new one.
And also for including an email address so you can get your password reset when you forget it. This might be more trouble than it's worth, as it'll mean you'll get generated a new private key, but no way of associating it with the old one. So all previous data is essentially orphaned. It might have to result in it deleting all links from everyone linking to you and then rebuilding them. Which is definitely not ideal. Probably requires more thought I think.
