by doing exactly what you are doing. Beg for them. Cry for them. Whine and plea and pine for them. Its the only way to raise it. Good luck, we've all done it, I can't wait to hear some serious begging for rep points from you. I'll be watching.
Yup, read that, you can either beg for them and people with pity will give you points. (like that would ever happen) Or, you could make a decent post that people would like and they might rep you for it.
