Example:
The total newsletter subscribers is 4839 multiply by 10 stakes, totaling to 48,390. If your one of the subscriber with 10 stakes, you can claim MNC at 10 stakes divided by 48,390 multiply by 3000 MNC [(10/48,390)*3000] = 0.61996278 MNC share.
This is just hypothetical example. Your actual number of MNC will depends on actual data.
So if you want to get more MNC, you should join most of the bounty campaign. We all have 11 days before ICO ends.
