The main point to note with this trophy is, you have to actually contribute something toward the community goal you have signed up for; signing up alone is not enough.
The trade related community goals are generally the easier ones to contribute to, lugging even 1ton of the listed stock market commodities to the appropriate starport will put you on the reward ladder proper, and this trophy will pop when the reward is collected.
You can use this link to help find commodities near the referenced community starport for the goal too:
