fun ways to sign a letter

over this past summer i became moderately obsessed with differing ways of signing a letter other than "sincerely." my list isn't that great, but it's all i've got so far. if anyone has suggestions, please submit them.

racially
with a little shade of red
consistently
characteristically
fundamentally
overwhelmingly
suggestively
biographically
evidently
technically
with masterful aplomb
how am i not myself
in a sentimental mood
jars and jars of stars
