FOSS gamedev and creative worlds

I am playing minetest for the first time and currently have 0.4.1 version. I tried getting materials but for whatever reason I have not been able to. I do not have it on create mode. Can some one please help me out?

It's creative mode and do you have a full inventory?

You need a pickaxe to mine stone-based blocks.
Also, see the wiki.

I figured out what was going on...ummm...me! hehe All I needed to do was hold down the mouse button until material would break. Thanks for your guys help. I really appreciate it. If you want to give me a hard time about this, I would not blame you guys. lol =p

You had a problem, asked for help, still had a problem and now you solved it yourself and learned from it. Thats great :-D
