I have over a 100 active member's, Most of which I have played with to insure they arent griefs or troublemakers.
I also run a Page for seed coordinates, posted in the group, including seeds found for End Portal Frames and other goodies.
Daily Updates, sometimes even hourly. Active group.
Please join if you are interested.
Also I have included a link to a page I run for 360 Seeds, I already have one up for an End Portal Frame, and one seed completely mapped out: Ie: Diamonds, Chests, Etc
All seeds are kept up with the UPDATES! :D
