Xper points are points you receive through various means
eg. posting a question, answering a question, having a certain amount
of people post on your question, etc.
Xper points will also level up your account which gives you access to
new features, such as sending private messages (lv2) or posting more questions
after Xper lv7, ads won't show on this site anymore.
Xper points can also be used to redeem rewards, such as
the much wanted amazon gift card.
Rest assured though, spending Xper points to redeem
rewards, won't have you lose levels. ^.^
Any other questions can be found
in the FaQ that the lovely @zombiebabe linked for you.2
