Solution button in beginner category posts

Discourse forum of rust users use the solution button for each post to indicate the post is solved.

This can be an encouragement for others to give answers (because it shows in person profile), particularly in the beginner channels.

Also, it seems the LLVM mailing lists will also planning to use discourse for all discussions. So It may be good to test this feature early.

Thanks! We had the plugin enabled, but it need to be also enabled in every category individually, I don’t know if we should have this everywhere or just in selected categories, but I just enabled it for the beginner one right now, see this answer where I tested it: Source-Based Code Coverage: Merge results from running mulitple binaries - #2 by zero9178

Thanks, It looks good.
