Hello Failular,
Well first off, Welcome to the Toribash Community!
In my opinion, the easiest way to get better in Toribash is to actually try to make moves, then try them in multiplayer, if you don't try them in multiplayer, then they probably won't turn out as you thought they would. As for your '50' post count by the end of the year, Thats actually what I told myself when I joined the Toribash, and after one year, I had about 800 :P so don't be surprised if you end up getting that many post counts in a year. I hope to see you ingame, so i can teach you some pointers
If you need any help, ask in the support area of the forums, or turn to a mod or smod. I hope you love your time playing toribash!
