Humm, I'm not with AdSense (explain why in a min), but i'm with Clicksor... I've reached my $20 a while ago and actually got paid (quite amazed). But thats only because I was getting lots of hits from Good-Tutorials, Pixel2Life, Tutorialized and so on. Now I just don't seem to have the time to write tutorials, now I'm actually getting clients. But I'm getting more from them than I ever could from ads.
Ok, I want to sign up for AdSense because I heard they pay more than Clicksor, so I submitted, they accepted me... They deposited some moey into my bank account, and I told them how much was in it (so I can be verified like on PayPal)... But then "Your payments are on hold" is still there because I have not submitted my tax information... Now, I'm a "non-resident alien" (aka British) to them, and I have to fill in this huge form with things on it such as my social security number (but i don't have one?!?!?) and then either send it by snail mail of by fax.... Now I was wondering If you all had to do this to be part of AdSense?
