I have a website krazycreditcard.com and it is not wordpress friendly someone told me I am not sure what does that mean. I have opened an account with the word press with the same domain(krazycreditcard.com), I want to promote this site. My question is do I have to sign up for another domain name and hosting company and link this site(krazycreditcard.com) when I post blogs or I can use the same wordpress account that I already have and start putting blogs on it. Hope it is not confusing.
Most hosting companies support the use of Wordpress Blogs. If your company does not, I'd recommend using http://www.ezspl.com. I use them. And they have Fantastico that can allow you to do many more things along with Wordpress blogs.
Installing wordpress is easy. download the zip file and read the read me file you will able to do it in no time.
