This already is a dating site.
Rules:
1. Being an INFJ means you have trust issues. That's why every member must pretend this isn't a dating site, even if you aren't an INFJ.
2. Most of the action on this site happens in private conversations.
3. You can start the mating rituals by posting an introduction thread, followed by posting your picture in the member photos thread.
3.1. At this point one of the regulars might already start a conversation with you about some not really private thing. It's just better to talk privately because INFJs hate so much how every thread is derailed, right? However, if your inbox is still empty, then it's better to start a support thread describing an emotional issue. Soon enough someone with the same experiences will rush to support you privately. Sure, they've probably mentioned the same issues elsewhere on the site, but it's better to provide support privately so that other people won't misunderstand all the kiss emojis.
You both know that it's just about being empathetic and not about looking for love, even though the relationship status has been clarified in the second message.
3.2. Start communicating on other platforms. Now you may start the relationship. It's time to let everyone know so that others on the site won't bother trying anything.
Am I cynical or just joking? I don't even know myself, but a lot of people
do treat this as a dating site while pretending not to.
Note: in case someone reading this feels this is a jab at them, I didn't write this thinking of anyone in particular. It's just what I believe to be a common pattern based on seeing how new and old single members generally interact.
