Question about attaining Trust Level 2 in the forums

When it says “Enter 70 Topics” does that mean create 70 topics or does that mean open 70 topics? I am assuming the latter because I have reached Trust Level 1 and have only created one topic when the requirements say to “Enter 5 Topics”.

The latter (I think). I haven’t even made one topic and I’m able to flag posts.

Yeah, that only means visiting that number of topics (not necessarily reading all posts there). This is reflected by when you enter / open them. There are no such requirements regarding creation of topics.
