You probably remember it from the old forums, but for those who don't here's how it works:
The first poster will write the name of a Pokemon. The next poster has to name another Pokemon, whose name starts with the last letter of the first's name, and so on.
Example:
Post 1:
Porygo[n]
Post 2:
[N]idokin{g}
Post 3:
{G}oldeen
~~~
Ok, let's start with...
Pikachu.
