Sure, For the long option folks, understand that options are not "investing" and learn how to manage your risk and bankroll. Unlike stock, options require correctly estimating not only the direction of an underlying, but also the precise timing AND magnitude of the change.

For thinly traded options try to never pay the ASK in a wide spread, shop for best price but know you are often working against a computer and its algorithms.
You can still be a bullish supporter and sell covered calls.
