So uhm, it's been 4 days without a response in any way from [@Thesurvivor] not in the PM's, not in the site I intended to use for the collaboration post, nor here. How much longer you guys reckon I wait? And how do I deal with it, since my character is IC talking to him?

He seems to have diasppered from the site for the time being, so I would recommend just getting yourself out of the collab and continuing it when he comes back. I'm in a few other RP's with him and he ins't responding in those either so.
