Horary is a branch of astrology in which a chart is erected for a certain moment in time in which the querent thinks of an important question; the idea is that the alignment of the planets at that moment, if the querent is sincere, will reveal an answer to that particular question.
The most common "incorrect forum posting" occurs when a member posts his or her natal chart in one of the various subboards of the Horary Astrology Board or else posts a relationship chart and asks a specific question about the relationship here instead of in the Relational Astrology board where it belongs.
Now, this does not mean that you cannot ask horary questions about relationships, but you must provide the correct chart--no natal or synastry charts, generally.
I hope this answers your question somewhat
