I've made some changes to MD 2011-06-01 to allow creative mode (unlimited blocks). Well, it's need some explanation, since enabling creative mode isn't as easy as put <Creative>true</Creative> into ServerConfig.xml. You'll need to change blocks.csv also or player will get only crafting table, crops and some torches at start (but in creative resources aren't removed). At least for now (maybe other dev can carry on it from now since it was 2hard4me even with exe's help).
Here are instructions on modifying blocks.csv so players would get all blocks:
You just need set in column StartInventoryAmount 1 for all lines. Then all blocks would be added to Inventory. Then put <Creative>true</Creative> in ServerConfig.xml and tadaam, resources are unlimited (when placing they're aren't substracted). This required modifying one file in source, so here you have it.
