well all i can say for now is wow, and when it come to AFFILIATE MARKETING there are dozens of places that accept Nigerians. you just have to do your homework(research)
i have already found many affiliate programmes that accept Nigerians and its much simpler cause your paid by means of check and on CPA basis meanining cos per action like referring someone to register.download,visit or even click on certain links
and i will be publishing most of them on my blog(www.dasilvareal.tk) soon
However about clickbank you only need a UK not US address as you might have noticed the other fellow complaining about tax id stuff, thats it with Us addressess and with uk u dont have to pay anything to get the address. to get the address goto (www./getukaddress)
i certainly hope ive been of help in many ways
rememeber the UKadress link is http://www.tinyurl dot com/getukaddress
