[Mediawiki-l] Renaming Wikisysop --> Bad idea?

[Wikimini]

Hi,

I'm going to merge my Wikisysop account (say "Larry") with a wiki user's
account (say "Jimmy"). As a result, I want to keep the name of the 2nd
account ("Jimmy").

Is that a bad idea?

Some more info : "Jimmy" account is a "ghost account". I created it but
never used it (contributions = 0).

I could do that with the User_Merge_and_Delete extension (
http://www.mediawiki.org/wiki/Extension:User_Merge_and_Delete). Maybe there
is a better way ?

I would like to be sure that this won't break my wiki. Thank you for any
advice.

Laurent
