Thanks for your feedback. I don't want to copy other tokens and still not sure that the front end is needed. Maybe this will be only a token that will rewards collaborations. I talked even with a few developers here and it seems that I have just to do it my way. It will be crazy a bit and maybe just an experiment, but it's better than doing nothing. I have nothing to lose anyway trying this. Maybe it will be valuble even if it's not following all the rules of investors !
