btw i don't think that there is something wrong with asking if there is going to be a discount. i did it by myself ?
in the end, if Erel has decided to put b4a,b4j,b4r for free it is his decision and i am sure he knew what he is doing.
but I also think that we need to support Erel more and everyone can decide how. like buying b4i or donating or contributing in this forum or creating lots of free sources so people will be motivated to try b4x.
