hmm just a few suggestions:
a.) it would be cool if there were a way to assign multiple names to one person. I might have a friend called Joseph, but i also call him J, joe, seph, whatever...it would be great if i could enter multiple names.
b.) it would also be excellent if it would still create the links despite differences in uppercase/lowercase. Now Joseph and joseph are still two different people, which means i have to remember if i entered the name in uppercase or lowercaseinto the db when i write my blog.
b.) it would be great that if i didn't have my nophoto image in the directory specified in both people-admin.php and people-popup.php then i didn't have to change it in both files, as i do now. You only mention changing it in the popup as far as i can see. If i only change it in the popup, i still have to manually type in /blog/images/nophoto.jpg when i enter a new person, instead of /images/nophoto.jpg. I found a hardlink to /images/nophoto.jpg in the people-admin and changed that and now it works, it has the changed URL in the textfield when i enter a new person, but that wasn't mentioned in the readme :)
c.) i installed it and it works fine but it started parsing the bios in the popup windows for names, too., and creating links, which is a bit pointless. so i commented out /*$bio = peopleDefine($bio);*/ from the people-popup and now it doesn't do it anymore.
d.) i seem to have real problems editing the people-popup. for some reason even though i have made changes they just REFUSE to show up, even though i have double and triple checked. SO far i can't find out why not. maybe thats just me tho, it wouldn't be the first time. ;)
but cool hack. i like it. I had been looking for something like this in a while :)
