I don't know if I'm doing this right since I'm a total wiki newbie but well, as suggested by Sandreen (thanks for your patience!), I decided to start a thread here about the volume summaries instead of flooding your message walls with duplicate posts :)
I will post here about the volumes I will be doing as well as doubts that I have about the summaries. Since English is not my first language and I am still learning it, I hope you can take at least a quick look at them when you have some spare time ^^
I've finished the summaries for the three chapters of vol 13 (this is the last volume I read) so now I'm going to proceed with vol 12 because I don't know when I will be having enough time to read vol 14.
