I have suggested to one of the RNS guys, that there is a weekly capfest in a different system each week. Everyone knows when it'll be... People can turn up or not turn up as they choose.
I would suggest not putting numbers limits on this fight, and regarding it as the "rules free" brawl. This way there is an outlet for the no holds barred approach, without it potentially upsetting the more "polite" general day to day war stuff.
What's going on with the GRN/BAF war at the moment is cool, because it's chilled out, and there is an understanding and dialogue between the participants. I'm quite keen to see it staying that way... So if we are going to have these mega capbrawls (which is no bad thing), I'd suggest they are done with the input and agreement of everyone involved, in order to avoid the whole thing turning sour.
This sort of thing can be arranged, and if the idea gets enough backing, then I'll set up the means by which to do it.
