We're always striving to improve Typepad and make the experience better for all our users. We're going to be making some changes to the free Micro service in the future that should really reflect this.
We're going to be conducting a thorough audit of our current Micro accounts and weed out any spam blogs that have made it through our registration process. This should cut down on the level of spam that we're seeing within the system.
We will need to close Micro registrations for a short time in order to make these improvements. We realize that this may be inconvenient, so if you need to sign up for a Micro account during that time, just contact us directly and we'll be happy to help!
As always, Typepad support is here to help whether you have a question or a comment on this or anything else related to your blog. Just reach out to us!
