We frequently have request for a new Forum or even Forum category where the discussion revolves around "how many people are interested." Forums have quite a bit of overhead and take up a lot of space on the screen. Those who are not interested in the forum content may begrudge the space and the need to visually scan past it. There is a feature of this forum software called "tags" that is similar to hashtags in social media contexts where anyone can make one up anytime they like. If others start to use it, it is described as "trending" which seems to be the major driving force behind ideas on social media. When you read a thread here on the Message Board there is a place just below the title of the thread where it may be "tagged" by anyone who wants to do so. In a recent discussion on having a Forum for Barometers, the discussion spanned off into clockwork toys and scientific instruments in general. I decided to use it as an example of what tags can do. Tags are general classifiers and the software treats them independently from the structures on the Message Board. If 7 threads in 4 different forums share the same tag, clicking on it in any of those threads will show the list of threads with that tag. This works essentially instantly since there is no need to search the database full text. Tags are "owned" by the person who put them on the particular thread. They do not own the tag wherever it appears, only where they have used it. The owner always has the ability to edit their own tags but not those left by others. Moderators and Admins do have the ability to remove tags used mischievously as part of the normal moderation activity. If you have an idea for a subject area or topic that you think would be of general interest like barometers, you may try tagging a thread with it. The software does dynamic searching as you enter your tag and may find that it has already been used elsewhere. Generally you should use whatever form of the term is already a tag to include more content. If you want to "prime the pump" for your tag, you might do a search for a phrase of even a word that represents the tag. If you then scan the search results you may have more threads that are appropriate for use of the tag. You can, of course, search for other related words or expressions that might appear in a thread instead of your tag even though they are on the same idea. I really would like to encourage people to think about this. If you come up with a great tag, you might even create a thread about it and why you created it just to make sure anyone who might be interested would be aware.
