I present http://wottactic.tk, a tool to plan your battles cws, stronghold and team battles. It's simple, fast and has more features that you probably need.
But don't take my word for it, go over there and give it a try, no registration or download required, just press the new room button, copy paste the link to a few friends and you're good to go.
Want your voice heard, fill in the short survey.
Enjoy.
