any place dedicated for that? I see people post it in the trade forum. Not sure if that is the right place to post.

You could join the gang - https://forums.d2jsp.org/topic.php?t=107743167&f=148

Or look for other discord groups, though groups are mostly running during peaks like reset, TZs *at least in previous seasons*, or extra XP events.

You can also join public games, add friends and try to find people who run what you want to.
