So is brain free? Like I hear people saying that it tries to get you to pay? Is that just for premium or no? Are the answers really unlimited? So should I join is it worth it?

It's like this, you have to have to answer other people questions in order to get points to ask your own questions if you get it.

answer; i believe the above is false;

no. when the asker posts the question they can make a question worth what ever they think is a fair price. although it must be within the limit of the points they currently own. 5 is the minimum number of points a question can be worth. if a question is complicated or has lots of parts to it, it is better to make it worth more because more people will be more willing to answer.

hope this !
