(I would also be in it, tho I'm not actually competing=) Many ppl might win me, cuz- there are a lot of people that are super good players in our group, which is wayyy better than me- yet I'm fine with that XD~~~~~ \nThough it's an admin tournament, pairings would still be based on rank! 19x19, so there will be handi-cap!!!",
