I have read on other websites where negative comments were made but they do not provide solutions to the ban nor provide ways to counter the ban via positive actions.
Giving away brochures about Dorje Shugden (which can be downloaded from this website here:
http://www.dorjeshugden.com/category/downloads/promotional/)
Help practitioners who wish to help the monks of Dorje Shugden monasteries (by financial means, or providing whatever they need to travel and stay at the monasteries).
Become pen pals of monks at Serpom or Shar Gaden Monasteries, or other Dorje Shugden monasteries.
Sponsor Dorje Shugden monasteries.
