Well, we tried to implement our own STEEM-Engine token, in fact - we thought of an interesting bonus system using STEEM-Engine tokens - but we basically hit a wall when we asked around for a capable dev or team of devs that could help us. For the time being at least, the costs of such an implementation are way too high and we are simply not capable of supporting such a cost. If you know somebody who could help us with implementing STEEM-Engine tokens at a more reasonable price, please contact us as soon as you are able. We are more than willing to listen.
