Actually, I have asked for this. Why? Let me explain it.
Go ingame right now. Do /who. Read the number of people there. Now go to the forum and look at people online. The answer as to 'why' there needs to be an ingame (and yes, ooc) message board should be obvious. ith active, or semi active RP event, or continuing ‘story’ type RPs listed with a short definition of each, and the 'link' to the proper thread on the forum, where most of the info can be found.
I have tried the /shout-forum method, and found it to be interruptive, rude, clumsy, narrow, and stupid. It does not work. It would be so much easier to just bring up a menu with RPs, GM or player, and look through it for something interesting that your character may have 'heard' about.
I have talked to many very good RPers who do not even go to the forums at all. Even when I asked that they do to know more about the Cold RP I was doing, they were reluctant.
Another thing is that there are many RPs that are posted in the forum that die before they are two days old.
I have an entire system of support for this that I have thought out, but do not have the time, nor want to post it right now.
So yes, it is a very good idea. The 'events' he pointed to are very simple examples. I tend to think on a grander scale.
