I'm new to WordPress, and I've been looking around for some good plug-ins. I found a couple, but they are driving me insane. Everything seems to require AJAX. I've done a fair amount of research, including here in the WordPress website, but I'm lost almost completely. I don't know if AJAX itself is a plug-in or what? I can't have some aspects of my site functioning because of this AJAX thing and plug-ins. Can someone please PLEASE enlighten me, thank you.
