Did you ever consider this?
This is community of people that share thoughts, ideas, laughs and, yes, we do at times bicker amongst ourselves. But, first and foremost we are a community that exists and, as far as the Internet might allow, are friends.
We occasionally have the opportunity to sell to each other but we pretty much know who we're buying from so this forum is not your local Craigslist of Ebay. Some stranger who comes here with the main intent of selling is not necessarily welcomed with open arms.
I see that the last time you posted was about five years ago and then they were fairly valid questions. You got your answers then and then you were gone like yesterday's train. Wham, bam, thank you ma'am.
... and nothing in the five years since then, until just now, when your came back to sell stuff. In fact, you've made more posts since you came back asking how to sell your stuff than you did when you had real questions.
The rules are posted as to what you need to sell and now that you've tipped your hat as to why you're really here, well, it might be a bit more difficult than before
