It is quite likely that his interest for the site has waned, you gotta remember Reltair made this site more than a decade ago, lad probably in his middle 30s now and has a family to take care of. With the apparent reality mentioned above, I think its pretty easy to guess why he had seemingly disappeared from the internet... as 'Reltair' that is.
The only way anyone could contact him now is through the site's email, which I think is more than enough since we only ever called him up when we want to delete threads.
Apparently RoadRunner found out that Rel still runs an online business of reselling figmas, I forgot the store page's URL but I do remember visiting it last year when Road shared it with me. And we know for a fact that he's been in the business since 2010s, perhaps even earlier.
So no, there's no new admin. I can tell you about Name though, he made javascripts that adds new feature to the site, albeit only locally on your own device. Reltair wasn't comfortable with the idea of updating the site, so Name took the matters to his own hands.
