I can’t find someone asking for suggestions either. I don’t think that’s what the topic started meant. If you want a suggestion you can look around in Lucid Adventures. The BIG Favourite thing to do in a LD and the BIG Quest Topic (links to all the LD4all Quests) are some useful topics to find suggestions. Or you can just look around in the other topics there.
I agree with what’s said. Suggestions can be great, because it gives you ideas. For new LDers it may be a way to get more motivated on what they want to achieve and see what the possiblities are in a lucid dream (they’re unlimited) and for more experienced LDers it may give new ideas to do.
