craigswan:But dodgy or Dodgy is a nickname so it is not a real name . So should capital be used in a nickname
"Wikipedia avoids unnecessary capitalization. In English, capitalization is primarily needed for proper names" https://en.wikipedia.org/wiki/Wikipedia:Manual_of_Style/Capital_letters
So, if dodgy is not a proper name, a capital is not needed. It is not a proper name, and certainly not a real name, like....who would name their kid Dodgy? (I tried to find one but couldn't). Therefore neither proper or real.
Now, lets presume it is being used in the descriptive sense, as in he has a dodgy putter, which, in this instance, may be the case, a capital is not used.
Further, lets presume that there are more than one, in fact hundreds of thousands or more, may be millions, they are so common, the word dodgy becomes synonymous with a specific breed, or sub-species, of human, like a pinto is as to the equine species. In such instance, and once again, a capital "D" would not be used. see https://uwf.edu/ >cassh>writing lab>mini-lessons.
NOW...
DodgyPutter: How do you know? :-)
As Mr. Putter has drawn into question whether it is a real name or a nickname, I would surmise that a capital "D" is optional.
Finally, if you search his member name via WGT player search, it works regardless of whether you use "D" or "d".
Finally...
craigswan: According to wikipedia
Wikipedia should be capitalized.
