The new Blogger
At this time, since this is such a large blog, this knit-along can't be converted. According to Blogger, if you switch to the new version, you will still be able to access this group, but it will still be in the old format. You will not be able to use the features of the new Blogger with this particular blog.
When this blog does switch to the new version, you will NOT be able to access it unless your account is also converted, unless you ask for an invitation and another is sent out. For the obvious reasons, I'd like to avoid doing this, so I hope that once I'm able to switch to the new version of Blogger, the rest of you do so as well.
The new version addresses one of the biggest things lacking with Blogger vs. other blogging software, and that is labels or tags. After the switch, it'll be easy to categorize old and new posts alike to make searching for information and seeing each other's progress even easier.
