When you start or post in a thread, you are by default "watching" the thread. Only you will see that eye symbol by your watched threads, so it's not anything to worry about.
Since I checked out your link, I noticed that you asked for PayPal F&F for payment. I'd recommend reading the exchange rules, because Goods & Services is strongly recommended here:
Be 100% sure that you want to sell the item, have it in your possession and clearly list the TOTAL selling price.
- There is no "testing the waters" or "gauge buyer interest".
- "Net to me" needs to be figured into your LISTED PRICE
- Insurance is the responsibility of the SELLER not the Buyer. This is for your protection.
- Paypal "friends & family" is STRONGLY DISCOURAGED. This is for your protection.
