Queeeestion. And possible suggestion.
Can you make a thread for something, and anything related to the thing, if it also a [whateverhere] and in the same theme, can other people ALSO post stuff to it if they've got one?
Since that doesn't make sense, could there be added another [thing] called themed? Where... anything themed a certain way, no matter if it is clothing or an artwork pattern, be added to it? I think that makes sense.
Sorry if this isn't the right place to suggest this.
