I want to say Five years ago i went somewhere, should there be a comma after Five years ago?

As in...
Five years ago, I went to....
or Five years ago I went to...

We usually don't use a comma after such a short introductory phrase.

In what exactly are you seeking membership, Dinae?!

Yes, there should be a comma after "Five years ago" in the sentence, "Five years ago, I went to...". When a time expression like "Five years ago" is used at the beginning of a sentence, it is generally followed by a comma to separate it from the main clause. This helps to clarify the meaning and improve readability.
