French language Q&A Forum

I haven't come across this before. Could someone explain it's meaning?

For some reason I can't reply to a specific response, so I'll have to post this as a seperate comment. 

This is a follow up question to Laura's translation of "She ought to really stop seeing him", which she wrote as "Elle devrait vraiment arreter de le voir." I'm wondering if the phrase "Elle devrait vraiment s'arreter de le voir" is also acceptable.
