Where do I start with scripting as a beginner?

I'm not really into this. May you tell me how to script like beginners?

Absolute beginner's guide to scripting

As spy said, LuaLearners is a great site to learn your scripting basics. It also includes harder courses as you progress.

the first place you should start is how to remove things. I even started learning to script like that. first, you need to know the name of the play arena. it is called Workspace. if you want to remove a message from the workspace you would first have to find out the name of the message, then you do this:

game.Workspace.Message:Destroy() -- the game is the game and workspace is the "play arena". the Message is the message's name. (although it could have a different **name**. you can use :Destroy() or :Remove() to make objects go away. 

Now that you know a little bit, go to www.lualearners.org to do the rest.
