eclipse error unbound classpath variable m2_repo

Everything was great until I changed workspace in Eclipse for other directory. When I opened th project I've got a bunche of errors "unbound classpath variable m2_repo". In this case do this:

1. Go to Preferences/Java/Build PAth/Classpath Variables
2. If there is no such variable as M2_REPO - add it (press New...)
3. Ussually a correct path for this variable is ${user.home}/.m2/repository

That's all.

I've changed view of my blog iPaniov.blogspot.com for a new dynamic view which I really like it, but there is no way to login. I spent some time until I understood that this view is for READERS only, so this why there is no login form. So in order to login to your blog on bloodspot.com you should go to the Blogger.com and do login there. Only this way you will be able administrate your blog.

I think there is the lack of clarification about this from the part of Google.
