Traditional and Simplified characters
Sorry for bringing troubles
Traditional or Simplified depends on location and preference. If a person use Chinese Madarin in Simplified Characters, he may prefers Puxian in Simplified. If he use Chinese Madarin in Traditional Characters more often, he may prefers Puxian also in Traditional.
Most who use Simplified can also read Traditional. For them, how to write depends on the IME settings.
I used Simplified daily, but I noticed Puxian wiki pages are more in Traditional, so I decided to use Traditional. However, the dictionary I use is in Simplified, so maybe several translations I edited may be in Simplified due to my carelessness.
As to the Latin writing system, it is hard for me to use, because the dictionary I use is in Chinese Characters. If bringing troubles, I'm sorry.
