Why: Been a while since I've played Minecraft and I miss it. Would like a vanilla server and not a bunch of mods.
Chat/calling: Yes I can call, but I probably won't be on voice chat much.
Hours per week: my work schedule varies a lot so probably between 4 hours and 14ish hours a week. In two weeks or so I'll have several hours free per night, but until then it will be less.
