Line 90 of GatherMate_Sharing.lua currently reads:
if not zone or zone < 1 or zone > 64 or zone ~= floor(zone) then
it needs to be changed to:
if not zone or zone < 1 or zone > 80 or zone ~= floor(zone) then
so that Northrend data is shared.
One small request...
It would nice if a chat message was displayed when you receive data from another guild member, so that you know you are sucessfully receiving data from other people. Something like this after line 113:
DEFAULT_CHAT_FRAME:AddMessage("GatherMate: Received gather of " .. GatherMate.reverseNodeIDs[dbIndexes[nodeType]][nodeID] .. " from " .. sender .. " in " .. zoneName)
