This is not really needed, but it's a little idea for everyone to keep track of the threads they join and open. c;
In case you have multiple open threads, it would be wise to order them in some way so you kind of know in which time line of your character they belong or in which thread you have to respond, so that certain threads don't go inactive and have to be closed without earning any experience points or overall skill points.
As said before, it's not really needed, but it would be handy to do so, just to keep yourself out of a chaotic mess. You don't have to put your open threads on here somewhere for you to keep track of, you can save them somewhere else as well, for example in a Word Document. But it's encouraged you keep track of it somehow so that your threads still get replies.
