@WlodAA I see that you have created the (peano-curves) tag. It might be useful to create also the tag-wiki or at least the tag-excerpt. It might help other users to use the tag correctly. (This is probably not a problem here, since the tag name seems to be descriptive enough.) Another reason is that the tags used on only one question are automatically deleted after certain time unless they have a tag-wiki. — Martin Sleziak Sep 11 at 8:01
