[LanX]: as long as he has votes left, the nodelet remains
[LanX]: There is a very simple solution ...
[marinersk]: Correct, so one workaround is to leave one vote.
[marinersk]: But I was looking for a more elegant solution. It appears noone online at this time is aware of one.
[LanX]: go to Nodelet Settings and click "All nodelets off"
[LanX]: SUPER STABLE!!!
[marinersk]: LanX++ LOL Yes, that is another workaround. :-)
[LanX]: strangely you can't disable the XP nodelet
[LanX]: But you can use CSS to hide it
[LanX]: and disoplay the data permanently in your peronal nodelet
