Inline comments or user wishlist

Hi guys,

for my wedding page, I’d like the visitors to left their wishes for music at a blogpost without subscription. Yes, I know SPAM and stuff, but thats not an issue due to the page would be deleted after half a year.

I’ve made a couple of testings with several plugins and the native commenting system. What fits best my requirements was “POWr Comments” plugin, but in the free account it only takes comments from logged on users. For my idea, thats another barrier for family and friends, if you know what I mean.

Do any of you guys have an idea of a plugin or even a keyword for what I’m looking for?

Thanks for all
