How can i have a helpful star?
That depends on how helpful your answers are....and if you actually give "stars" out to people. Some people seem to be rude that way. I just gave you your first star on the rain question! You are on your way to a thousand soon :D
By being helpful?
By being helpful. Just answer questions and if people think you're helpful they'll give you one.
Gotta give good answers, look at Sunny's Gold Star, watch this ... BAM! ... Ok, now watch Epic' gold star ... BAM! ... Ok now watch Helix's gold star ... BAM! See? Just like that!
Tony, you always crack me up!
By giving good, correct and helpful answers.
What they said ^
I just checked your profile and guess what I saw?! You got a helpful little star! It's kinda cute too...
answer a question that is useful for the person. often time, people answer the questions stupidly, so you cannot really expect to be considered helpful.
Just give great answers that are helpful or fun. People will notice.
You can earn helpful stars by being helpful. :)
