Anyone is very likely to rank up, people say it clearly and it's true I think if you all care about post quality.
You are one of those whose rank up made me happy. Your year of registration dated back like mine and the slow pace to rank up was like mine too. But eventually you made it. Only those who make efforts will rank up, not just everybody. Celebrate yours anyway you like, there is nothing shameful about it. Keep making meaningful posts as usual. Your contributions to the forum is noted and can not be neglected.
