This has great options. I like how easy it was to setup. I can't understand how some of these reviews say such bad things about this plugin. I did have to wait like 10 minutes for it to show, but that is no big deal. I am a little patient sometimes for no support response quick, but I think some of the people that expect the support from a free plugin, needs to chill out.
I can understand if it was paid subscription or something like that or paid host for support, and not receiving a response fast enough. Some people are busy. If you want to know really slow response from support try using DISQUS comment system support. I am using that plugin and love it, but they take more than 24 hours to email you back after you fixed the problem yourself first, and then keep emailing days or week later after telling you fixed it already.
