Think of it more as a work shop where the various rp guilds & non-guilded rp'ers can work out just the bare bones of an idea for event(s) that they want to be public, or that they want another group or groups to interact with them on.
Recently I received a PM that I thought had some fantastics ideas for good vs. evil scenarios. Now I can PM these ideas to some folks that I think would be interested (and did), and get their opinions but that is only hitting a small group of people.
If we have one place to share ideas, get feedback, gauge interest, find out who is actually interested enough to go forward with it I think it might save time. In game meetings are great, but not everyone can attend, PM's and ICQ are great but by their nature are exclusive.
A neutral forum might also allow more parties to become interested and involved, and I think it might also reflect well on our shard, for people looking for a place to rp.
Yeah, I kinda dread another forum myself, but then I think how convenient it would be to be able to check it from work, and post from work, or late at night when I should be sleeping and most sane folks already are
It won't be a cure all for everything, and it may have it's bad as well as it's good, but I think its a good place to start building some bridges.
