is it too late for sig campaign?
you must reach membee rank before you can apply for waves signature campaign.
3 more post you arr about to member rank.
How can I check my member rank and progress? It measured strictly by the number of posts?
Not entirely. Here is some explanation.
https://bitcointalk.org/index.php?topic=237597.0From what I can tell, your account has posted in about 10 2 week periods. So your time*14 =140. However, your account only has 48 posts. So right now your activity is 48. (It's the smallest number between time*14 and number of posts.)
You can potentially rise up to full member in a short amount of time. Please don't spam, though, to do it. Could get you banned.
