And one more thing, avoid things like what _BlackStar said above.
Not mandatory, it's just a advice for him - this forum lets you discuss freely anywhere as long as you stay on topic and don't spam. Only if the OP wants to have lots of posts noticed then posting on megathread isn't going to get him what he wants. All posts will be buried with thousands of other spam, so the advice is avoid.
I still have 18 sMerits that can be sent and must be sent for the merit system to run smoothly.
Spend it on posts you deem quality, saving it won't do you much good and also not in your favor.
There is no point in hoarding sMerit; keeping it yourself does not benefit you, and we reserve the right to decay unused sMerit in the future.
