Some forums allow one to click an icon associated with a reply that indicates the reply solved the problem (or is the best solution…).
A lot of Community posts are problems that a person has run into using Haiku. Since there does not appear to be any indicator when the problem/issue is resolved, people searching the forums looking for a problem they have encountered (everyone searches before posting, don’t they?) cannot pick topics that might resolve their own issue.
One simple solution to this issue is for the original poster to modify the topic title to reflect its state. As an example, I have been using a keyword enclosed in brackets (preferably prefixed). A very short list of keywords could be added to a pinned topic. Here is one that could be used as a starting point.
