It's been few week that I'm reading posts here, but unfortunately it seems that a lot of the interesting one get closed down. Either for being to broad or intrapersonal instead of interpersonal, but why shouldn't this forum be broader ?
People come to seek for help regarding their relation, why are those off topic when people are not here only about their interpersonal relation. If you're talking about your relation with other it is actually interpersonal problems. We all know there's not exactly such a thing as interpersonal skills : you can't learn that as your learned math or coding or whatever, but there's indeed interpersonal problems and there's some way to solve them, and there we can help.
Of course we shouldn't say: do this or do that, but if people are asking about advice on their relationships, we should definitively give them and it's not off topic. Even when they are opinion based why can't them be relevant ?
They end up here because they want some help; why couldn't we give it to them ? It's sad, because in the end OPs end up transforming their originals question just to stick to the "rules"...
