Hey I just thought this might be useful, if you read the servers help section it lists a give commant in the way of.
Give (player name) (ID), with ID being the ID of the item you wish to give. So for example if you wanted the player Thomas to receive whatever item number 15 is you would type in.
Give Thomas 15
This would cause a block of whatever 15 is to fall at their feet (in this case an iron ore block). For the sake of it I notepadded a quick list of what all the numbers I could find are.
Edit: Someone in the thread linked me to a wiki page that had the internal numbers for several items listed...so I went ahead and tested em all and entered em as it was. As a note 36 is supposed to be white cloth on the wiki...but 35 spawns the white cloth (which is supposed to be grey cloth) the wiki notes the fact that alpha sees number 35 as white cloth...so I'm just making a guess that 36 might become grey cloth if he dosn't switch things round.
This is awesome. I copied the codes into a txt file and have it open next to my server window for quick reference. Now if I could get a complete list of commands like say, give, tp, etc. I've seen some lists by rank but I know there must be more commands than those.
