Rp Tutorials

I apologise if this is not the right place to post this question, but it seems like this is the most informative place where RP on IJ is concerned, so I wanted to ask if there were any comms on IJ that were for advertising PSLs that focused on world-building. Or are world-building/ original lines just not popular enough anymore to need its own community? Thanks in advance for the responses (if I get any)! :)
