Nearly everything discussed on this thread is relative. Whether or not someone here speaks to the opposite gender in real life or online and whether that’s ok or not depends on who the person in question is. So undoubtedly, if someone feels that the Coffee Room is an issue, (s)he should not be on here. For people who do not speak to the opposite gender in real life, whether or not they do on this thread is up the person to decide what’s best for them and what fits with their personal hashkafa. Luckily, the Coffee Room is appropriately moderated and everything here is kept within reason. A possible question would be, however, if because this is a Yeshivish-run website, if it is appropriate for them to give this impression to users that inter-gender (even within these boundaries) communication is permissable or not.
