The bell icon shows you will be notified if there is a response.
There are a lot of experienced members who post on this forum but contributions are usually intermittent depending on what people have going on in their lives, so if you have a slightly more niche question (there aren't many with cob experience on here for example) then it might take a while before the relevant person checks in and sees your post. Usually as darker evenings draw in and people are limited in what works they can carry out, participation rates tend to rise.
This is a forum of like minded individuals rather than a technical support service, there are no SLAs on response times! If you are lucky you might post just before someone who has relevant experience logs in and you might get an answer in minutes, in other cases it might be days / weeks.
Making the post as easy to digest as possible, and including photos is always helpful, also searching the forum before you post often finds an answer from someone who has had the same issue before (or perhaps not in your case)!
