just wanted to share this little bit of information regarding water griefs, for those of you who may not know this is an option. this came up on github recently as a bug report relating to the issue where not all the flowing water will dissipate when you remove the source block... one person said just use world edit and //cut to deal with it - and that's fine but if you have a build in the way that you'd like to preserve, there is an alternative. this article goes over the IMeta assignments for flowing water... essentially what it says is that meta values on ID 8 are assigned to varying levels of flowing water. so when you use //replace 8 0 - you're only dealing with ONE of the many values associated with flowing water (8) by replacing it with air(0) to completely remove the water within the selected area, you'll have to run the //replace command several times, each time using a different meta; 8:xx as well as 9:xx. cheers, -u.
