Anyone care to chime in with first hand experience as to what things actually affect contributing to a base, rather than things they suspect affect donating to bases?
As far as i know from personal experience, only previous base donations of Energy, EM or CTP should affect your ability to donate to another legions base.
I can say for certain that "using" a CT Lab or using Clamps does not.
Discovering a CT Lab Print might though.... done that lately?
