Search Bar
On the top next to that /jo room section. Their should be a search bar to search for certain members or threads. You can suggest alternatives such as Google but Google doesn't always contain all members and/or threads. Especially if there are a lot of threads with a similar name (I tried searching for a member yesterday to send them a message but I couldn't because I couldn't find them on Google so I had to go through threads to find them). It would have helped so much if all I had to do was search their name on a search bar on the forums.
As far as what comes up when you search for them/thread. Their should be two sections, a section which shows members with similar characters to what you entered and a section for threads with similar characters. When I say similar characters I don't mean so that typing "ishi" will bring up users or threads with I,S,H and I in their username/title. It will bring up anything similar, if that makes sense.
So yeah, please do not suggest alternatives/unsupported because you find this useless to you, it may be useful to others.
Before getting upset about an idea that would be disadvantageous to you, consider the following:
If you think something will ruin the game, it probably wont be added.
If it is, it'll probably be optional and you wont be forced to use it.
If it's not optional, it'll probably be a minor change.
