I have been using the site for several weeks now (since the end of august) and I noticed some differences between pindiy and this site that make gaining credits to level up very hard.
You can get points by visiting other people walls but not for sending greetings as is the case with pindiy.
Also there is no way to buy the red envelope and put it on your wall for the visitors since it says that is out of stock.
There is also very little to do in the way of interaction to gain pins since you need to upload 4 books to gain 1 credit.
10 comments to gain 1 credit is very difficult to obtain since you have very little interaction/posts to comment on in the free talk, the rest are the posted books.
Is there another way to gain more credits.
When someone visits this page from a link you share, you will be rewarded
1.5 hour on the site gives you also a credit.
The simplest way to get credits is to thank people for sharing books.
With 10 "thank you for sharing", you get one credit....
As Caro1970 said, there are also the other sections.... I had a quick look and there are more than 45.000 threads in the different book sections...
And for the new books, it depends on the moment... but sometimes there are more than 100 a day... but quickly moderated to place them in the correct sections....
