I posted this question a couple of days ago and got some nice replies. However, for some reason, I cannot continue the conversations (replying to the replies) because none of the options for doing that are activated, even the 'like' button is not working.
In addition to the one you linked to, Elena, you also started 5 other threads including this one. Go back to the one you linked to and make sure you are signed in. If you are signed in you will be able to reply.
