Collaboration 

Hi Jayant. Let me unconfuse you about the whole collaboration thingy. It basically works like the Article Improvement Drive, where people vote for an article they really really want edited. You can still edit other articles, & you don't even have to edit the article nominated, but it just helps focus the group's attention at improving a single article. So continue editing as you were, & feel free to vote or edit the nominated article. Thanks,
