I was wondering if we should be doing edits such as https://anime.stackexchange.com/posts/2549/revisions. It only changes 'chakara' to 'chakra' and 'Jiraya' to 'Jiraiya'. I think that we should avoid making edits which only changes romanization, because it can lead to unnecessary ill-feeling, and potentially drive users away if it is done too often. I suggest that when there is no one correct known romanization, let the OP keep what they used.
Thus, for example, in Naruto, don't change Hyuuga to Hyuga (or vice versa), but changing Peine to Pain is okay, because that name intentionally uses the English word Pain. In your own answer though, use whatever you prefer (or even switch to OP's preference, if you wish).
No offence meant to Chetter Hummin, who is obviously trying to help.
EDIT Based on Logan M's answer, I think the example chosen is not a good one, so let me try with something else. Fairy Tail will offer plenty.
- Jellal or Gerard?
- Juvia Lockser or Loxar?
- Gray or Grey?
- Carla or Charle or Sharuru?
- Wendy Marvel or Marble?
- Ur or Ul?
I respectfully disagree that we should prefer whatever Google search prefers (I know Logan M didn't imply this). Users who read scanlations or watch fansubs are likely to be familiar with one or the other, and I think we should we should be open to everyone. Of course, as mentioned above, if one correct agreed romanization is available, we should use that.
