Both Ramiro and PrinceGupta are right. It's his life. He would do what he want to do man. Nobody have rights to negatively judge his decision.
He was here for 5 years almost. He give many things. Contributed as much as he can in his part time.
About sharing tools, It's his property he should share or he shouldn't it's his decision and totally his decision.
Yener left people have to move on and then Razor comes gives his contribution, he got hurt of something, he left, peope have to move on again.
he is studying engineering, still he provided many tools in his part time.
his decision is absolutely correct. And like other great contributors he have to focus in his real life which is good and this is what he is doing I think.
Many people in this forum tried to bring him back, Good thing, he haven't replied simply he doesn't want to come back that's it, now what people should do one thing, move on.
Respecting Someone's work and his decision this is what some people should know here.

This topic is endless and will be.
