Two ways:
1.
@Martini Henrie could copy the link from the status bar in their browser and paste it somewhere on the forum.
2. Go to Underhive Tools, then click on Gang Browser and locate it.
It would help to know the Gang Name, approx date of creation and if it’s classed as a Custom Gang or based on an existing one.
I looked but couldn’t see any custom gangs created by the OP. It doesn’t help there’s no obvious search function though.
Once you do find it, you can open it, then clone.
Like this one I found:
Custom gang with a rating of 1240 by Michaluch
yaktribe.games
I’m not sure how to clone fighters in the gang though - in case you want two Orrus but none of the others etc.
