what would happen if i make a thread in the wrong place?
It would then be moved to the correct location. The most important is to use a relevant/original title as described here: http://www.essayforum.com/subject.html.
oh, and... do we actually need to pay?
You'll only 'have' to pay if you'd like to remove your essay that has already been commented by other members. Using site is absolutely free.
