Lajkuj Plugin 1.0
A basic "Like" functionality similar to the one of Facebook, but instead of interconnecting with Facebook with their "Like" buttons, I just implemented the functionality into the forum. Should work without any additional configuration, although I only have two basic Vanilla 2 installations at hand, so some more obscure environments might not work. Also no optimization in terms of speed on huge databases etc has been done, as I don't have no such environment at my disposal.
Feel free to contact me in case something does not work for you, but best if you look inside the code first, as it is really rather simplistic and you might find the help you need before I could even get to read your mail.
And hey, since I believe it's become sort of a fashion, ME NO GUARANTEE NUFFIN TO YOUS )
