When people post a thread to look for opponents, the thread title usually reflects which game(s) that an opponent is wanted for, making it easy to see if it might be something of interest.
To make this even easier, you now have the option of tagging (prefixing) your thread to indicate which game you are seeking opponent(s) for: [WIA]
In addition to the game-specific tags, you can also tag your thread as [Multi]
if you have more than one game in mind, or you can tag it as [General]
if your thread isn't addressing specific games.
I have hopes that this will make it even easier to find opponents, since you can use this when searching and also in filtering the threads displayed when you access this forum
As for existing threads, I'll add tags for the first page here; if anyone feels a need for tags to be added to older threads, let me know
