Im a Second Life sim owner. Can I promote my sim on Koinup?
Yes, sure. Firstly you can add your sim on Koinup, by uploading pictures and adding the exact SLurl to them. And you can also invite your friends to do the same. Cause, the most people will share that place, the most it will listed as coolest, getting much more traffic. But you can also consider to advertise on Koinup, more info here.
