Hi, Your idea of putting a weekly set review is interesting. It's very interesting to discuss set with other.
But I have a suggestion.
Why don't you put a section for set review, and in this section, make a topic for all set. Instead of a topic mixed with other.
I like your idea of weekly review. So you can put a new set in this section each week. And peoples could talk about the new set of the week, an about the other set you put previously.
I have an exemple (not related to lego).
This is an exemple in music, where in the album section there are topic of each album. This idea can be used with the sets.
Tell me what do you think ?
