Previously I wrote up a post asking if people would like weekly - now fortnightly topic challenges. The answer from the community was a resounding yes.

So today will be the second one. As per some of the suggestions, I'm going to start with tags that have seen a decent amount of activity but still aren't commonly used. For the next two weeks, the tag will be , as suggested by Mourdos, who wrote:

Because it hasn't seen much use and plant life is an important aspect of any world.

Remember to use this tag if you're asking a question as part of the challenge.

In two weeks, I'll announce the stats for users who asked and answered questions using the tag. If you have questions, see the original post or ask in chat. Let's build some new worlds!
