Thanks for answering :)

I've read something about canceling points for your content, but you can still win points by participating in some contests, am I right?

And that Sola interface is quite confusing to me, I don't know how to approach to see all the topics or autors, it's pretty much different from Steemit. On the first glance it looks like it's all about sliding random photos and that don't have much sense to me.
