It is not that much easy to get merit. At present except posting quality posts no option left for all members to get promoted. And the fact is seventy present of the bitcoin forum members don't know and practice proper English including me. So this is not going to be easy our life. Only time has to tell about the future.
There are some smerits review by the people in this forum on services section. So you guys may try to share your post which are all you think as a quality post but still begging is not that much recommended.
Just write and ask to review your post post. If the op like the posts you may get the more number of merits from that person.
Good luck for it and then concentrate on the technical related assistance thread. That may bring more number of merits.
