I am also new here as well and can address a few of your challenges. You can edit a post after you have posted it. If you are not using the eSteem app created by @good-karma i suggest you download it and start using it. Its very efficient as i have come to see it. Again,you can search for anything else by using the search tool on the browser, anything you type there will definitely give you some feedback. I hope i av been helpful enough.
