I think there should be alerts for when someone posts on your thread.
I just find it annoying to have to check my threads (not that I have that many anyways XD) every hour to see if someone has posted, and I think this would be a very useful feature.
I realized that it could get annoying if you have multiple threads that are posted on often, so maybe it could be a feature that can be turned on and off.
And if you're keeping an eye on a particular thread, like a roleplay, you can select if you want to receive alerts for posts on that thread.
Just an idea ^.^ And sorry if it has been brought up before DX
