Can you help me customize a badge and create a badge?

I can't give you exact examples anwsering straight to your questions right now but:

1) You've got translation marked string on osqa/forum_modules/default_badges/settings.py@58

class NiceQuestion(QuestionScoreBadge):
    expected_score = settings.NICE_QUESTION_VOTES_UP
    name = _("Nice Question")

There should be some simple thresholds settings in admin.

3) You can create "Amazing Question Badge" based on some badge which inherit from "QuestionScoreBadge" like the NiceQuestion badge mentioned above in osqa/forum_modules/default_badges/badges.py

2) "Forum Ninja" would need to get into badges most. Sorry for somekind of fuzzy anwser in advance.

• You will need to create ForumNinjaBadge in osqa/forum_modules/default_badges/badges.py which inherits from intermidiate badge layers like QuestionScoreBadge mentioned above or straight from base Badge class called AbstractBadge. Look into other classes there for some idea how it works.
• Add settings in osqa/forum_modules/default_badges/badges.py for your badge
• Tie badge to some action propably Karma points save at some point in OSQA to trigger badge awarding.

There is also similiar question if you look for more badges customization (if you haven't already visited it yet).
