Peacefulbird, not to discount what you just posted, but the previous post bumped up a thread from 2012 and it's spam - see the discreet link for 'help with an assignment' ? I mostly only lurk here but notice there are more of these spam posts lately. They do this to drive traffic to various websites. These posts are very sneaky because they can look legit, but the pattern is that they are from newly created accounts with very few posts and they contain discreet links to random websites.
Thought I would post this in hopes that others seeing them report them like I do.
