Hi Erik, welcome !
As to the current activity here being mostly related to the rendering of the Mandelbulb and Mandelbox - that's basically "extra" activity over and above what normally occurs here

Feel free to post parameter files for sharing and/or peer review or help, with or without specific questions and I'm sure you'll get some responses.
As to places dedicated to parameter sharing etc. then the best places for that are the Apo and UF mailing lists:
The UF list is:
ultrafractal@lists.fractalus.comI'm not sure of the address for the Apo list as I'm not a member.
To subscribe to the UF list just send a mail to
ultrafractal-subscribe@lists.fractalus.com (using the mail account you wish to use for UF list purposes). Currently the UF list is running at around 5 to 20 messages a day but sometimes there can be a lot more
