Greetings, congratulations on sharing your first idea with the community. We hope you found it an easy learning experience. Hope to see you post more.
Don't forget, as a PREMIUM MEMBER you CAN advertise your website, youtube, twitter, discords, signal services etc etc but ONLY in your user PROFILE SIGNATURE which has the advantage of appearing on all of your posts. You can update this as often as you like and all past posts will have it added and updated as well.
Just go to your USER PROFILE -> PROFILE SETTINGS and update everything you can under your public info, and also your user status. This will give you the best exposure site wide, and help you attract new followers if that is your goal.
