As a relatively new user of the site I'm puzzled.
Take this question as an example.
I looked at this and determined that it's a question about migration so I flagged it for migration and left a comment suggesting the OP repost. While I was doing this another member has posted an answer.
Now, the answer is fine, but it seems to me that by answering the question on Travel the incentive for the OP to repost on Expatriates is removed. This reduces the traffic to the Expatriates site, and blurs the distinction between the two sites.
There are comments elsewhere on this Meta about the beta status of Expatriates and the need to generate traffic there before it can graduate.
What is the policy here? Should I flag questions like this, or just ignore them. Is it appropriate to answer them here, or should those who answer be more encouraging to migration or repost?
