s#^(OBX\|[^|]+\|)([^^]*)#$1 . join("",map( { s/([A-Z])/U$1/ || s/([a-z
+])/L$1/; $_ } split //,$2)) #e;
OBX

  • Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
  • Read Where should I post X? if you're not absolutely sure you're posting in the right place.
  • Please read these before you post! —
