***** NOT A TEACHER *****
Tedwonny,
(1) I did some research and am delighed to share it with you.
(2) According to the Learner's Dictionary, me and myself are "correct."
(3) I also checked the many books in the Google book section and found that
"me included" is used by many writers.
(4) I also found one very strict teacher named Don Hoeferkamp in his book A
Lighthearted Book of Common Errors (2011), page 59. He writes that "myself"
is not a "stand-alone subsitutute for the personal pronoun I or me."
(a) Mr. Hoeferkamp says that we should write "I included" or "including me."
(a) I checked the Web a bit but could not find any examples of "I included."
(b) I personally believe that he is "correct" in terms of strict grammar, but nobody
seems to follow his "rule."
(5) So I guess that we can say:
Everyone was there, me/myself included.
Everyone was there, including me.
Everyone, me/myself included, was there.
Everyone, including me, was there.
***
And for those who have the courage to follow Mr. Hoeferkamp's advice:
Everyone was there, I included.
Everyone was there, including me.
Everyone, I included, was there.
Everyone, including me, was there.
(6) I also learned that "included" is analyzed as a postpositive adjective.
That is, it is an adjective, and its position ("positive") is always after ("post")
the noun/pronoun.

Many people found your question very interesting, I included. :lol:
