For many people the prospect of getting a domain name and hosting account with the promise of one click installation and hey presto you have yourself a blog and ready to go is all too tempting. But I have bad news for you.
One click install leaves your blog compromised and open to attack from hackers, and believe you me this is not a scare tactic to get you to purchase an installation service from me or any other service provider. If you can do it you are better off installing your blog manually yourself.
