How many postings do I need to post in 911 Used Parts For Sale & Wanted?

[p1973rsr911]

I have tried posting in "911 Used Parts" but nothing shows up. How many postings do I need before I am considered legitimate? Am I better off just using another popular Porsche forum?

Would like to sell a few 911 turbo items like:

FS: 965 Turbo Control Unit 965.618.130.01

Out of a working vehicle which had its engine management changed. Believed to be working but I don't have a way to test it.
Selling for half the cost to get a rebuilt one from AutoECMS
https://www.autoecmstore.com/products/965-618-130-01.

Asking $463.00 with shipping.

I can remove the cover to take more pictures.

Located in the Boston area.
