I put your 2 suggestions together since they were similar.
In a future version of Pokebase we will have a notification when people reply to you (i.e. answer your questions).
I don't think I will add an alert for when any question gets asked. You can just go to the Questions tab for that.
Same for points, it really doesn't matter when you gain a few points here and there, I think it will be annoying for people and make them take too much notice of points.
