I'm trying to set up a blog on my own hosting, and have discovered that the blog appears to use it's own user accounts, which are stored on my server. I actively would prefer not to use this feature (as it is perfectly possible that I will want to add accounts to the site in the future, since this is only a small portion of the site), and would like people to be able to post directly from their WordPress account, rather than having to make a separate one for my site specifically.
Another reason I have an issue with this is because of the Data Protection Act. Storing personal data (including e-mail addresses) requires that I register, and to do so costs money on a yearly basis. I would prefer not to have to register for a system that I don't particularly want, and is definitely not necessary. Is there a way to get around this, or do I just have to bear it (or use a different blog system)?
