You don't need a referral, you just go to the site and sign up.
It is definitely possible to earn money for October. Just make sure you take note of the terms for whatever site you are using, some take a month or so to receive.
Great free earnings lie in the daily greenfield, your2cents, otx type of surveys.
Also good to note: you can only complete an offer once. Meaning, if you do an offer on Sunshine Rewards, you cannot do it on Quick Rewards, etc.
And daily surveys: use the same email and info every time.
Only one account per household....and things track by i.p. address...so for instance, you can't do an offer on SR, and then your hubbie do it on QR, b/c it will be coming from the same computer/house so considered fraud.
Get a generic email account from someplace like yahoo, gmail, hotmail, gmx, etc. You will get alot of spam, so don't use your regular daily email.
I have not had any issues in two years getting any spam at home/snail mail, so don't worry about that.
You may get phone calls, so you may want to look into a free voicemail service to avoid "dinnertime" calls. Then you can go on and listen and reply to anything you are interested in.
Main point: use all real info, valid emails, addresses, phone. Otherwise you could be banned.
I have great success with Sunshine Rewards and Cashduck. I've heard good things about QR, but never used them so can't comment. Just be sure to keep things separate. Like, the things I do on SR I always do on SR (shopping, etc), the things on CD only on CD (AMP, your2cents, certain freebie types) so I won't accidentally do an offer twice.
I earn about $60/month. Some months more if I win a contest or something. Nothing to quit your dayjob over, but enough to sweeten the disny pot
PS: I think it is against board rules to ask or offer referrals...
