Not sure if you are aware of this or not, BUT...

When a poster uses special formatting (like center) as you have done, and does not close the command, i.e., open bracket, forward slant, "center", close bracket, then it causes the subsequent readers to get a screen in which all content is centered. In this instance, centering is a also justified.

Not a big deal, but when most of the formatting codes are not ended, then the formatting carries over to the pages viewed by others.
