Cannot be merited right now because it contains a mistake : a period doesn't start exactly since your registration on bitcointalk, it is a fixed 14 days starting with Tuesday at a precise time. You can join at the beginning of a period or before an hour from the end, till you made at least 1 post it is the same, both can have max 14 activity.
Will give the reward (1 sM) once this mistake is corrected to avoid confusion
