Unable to do any tasks

Refresh page often you are probably low lvl and low lvl competition is quiet fierce.... as you do more tasks more tasks become available. So yah check every day few times coz you never know when tasks going to pop up, also when they do many players already camping to do them as soon as they apear. So yah begining of tasking is very difficult check for tasks often and hope you get to do em before others start hording it.
