Bukkit

Players should be able to use any ordinary ore (as defined in the cfg)

Claim size to be set in the cfg file.

Able to define multiple ores (different claim areas)

I do not want them only available from a shop.

I like the idea of freedom to use predefined special blocks with dependency on lore or name or just have default blocks to act as a protection block.

In relation to http://dev.bukkit.org/bukkit-plugins/libelula-protection-blocks/tickets/25-command-to-give-players-protection-blocks/
I would like to see this. So there is no need to create a special command within Libelula Protection Blocks.
Just predefine in config something like this:

- Diamondore (or with block ID)
  name: Small protection
  lore: Put it to the ground!

Leave name and lore blank to allow default blocks to be a protection block.

This way they could be sold or given to players in various ways like with 3rd party plugins that can sell/give players items with name/lore in multiple ways (signs, command, step forward and jump, whatever).

That is a nice idea.A bit info on the lore would rlly help the players and the staff.Thumbs up
