I want to know how you post reviews on TMS. Not posting one in the advertising for players section (which I already did), I mean where all those people who look at TMS will see my review.

Click on the "INFO" for your game in the mudlisting, then click on the "submit a review" thing at the top of the info "sheet."

If a "submit a review" thing is missing, it means (as far as I know) that the MUD's implementers don't want anyone reviewing their game on TMS.
