Welcome to Noobstown! To look for a town type in-game /town list then when you find a town with (open) on it, then type /town join (name of town) If the town is (closed) you will need to type /town (Name of town) and messsage a TA/Mayor to invite you.
Then type /town spawn (name of town) to check the town out, or to go to your town type /town spawn
Enjoy.
