I know the SE protect users' privacy, so the lack of instruments to contact other users is a feature and not a bug. I respect that. However, recently two users (one is me) have shown interest in a stastical model which doesn't get a lot of love here, even asking similar questions, though I was careful to frame my questions in a way that wasn't strictly programming-related. To cut a long story short, the other user's question has been put on hold, and I think it will be closed soon:
It seems that I cannot create a gallery chatroom from a question put on hold. I also don't like the solution of commenting her/his question proposing to join me in a chat, because this is against the site policies. Do you have any suggestions on how I could try to let the OP know I would be glad to get in touch? I know I'm asking something against the site etiquette, but given the specificity of the method, and the rather remarkable fact we started asking about it at the same time, I think we could both be interested in collaboration. It could even be possible we are working on the same project - it's a big international collaboration, and it's possible (though a bit weird) that individuals from two different teams in two different parts of the world are trying to work on the same part of the project.
