We've discussed this issue in the past, and I think Mike and I have made our thoughts and opinions pretty clear on this. I'm not speaking for Mike, or any other C-Brat for that matter, but I believe the decision to unify or keep the C-Dog site going lies solely with those who participate there.
We've made it pretty clear that we're a warm and welcoming group. Folks who participate exclusively at the C-Dogs should have zero concern about whether they would be welcome here - they would.
One of the items often mentioned is the "regional issue". From what I've seen, this is less of an issue than it used to be, at least here. We generate quite a bit of discussion for California and certain East Coast gatherings, which used to be handled primarily at the C-Dog site.
Regardless, the regional issue primarily applies to gatherings. Just about everything else we discuss is relevant to everyone. If there's an interest in having gathering discussions more geographically focused here, that could be easily done. One possibility would be to break up the C-Brat Cruises and Gatherings forum into 4-5 regional forums.
From a technical perspective, consolidating the site activities is simple. However, I think the whole C-Brat / C-Dog issue is really one of identity. There may be individuals who will never feel comfortable calling themselves "C-Brats", or attending a something dubbed a "C-Brat gathering". And while we'll welcome anyone regardless of what they wish to call themselves, there is a lot of pride in the C-Brat name and all we've accomplished as a group - the name is not going to change.
So again...it comes down to what the C-Dog members wish to do. Personally, I've always hoped for a single group, and hope they decide to join us...but it's not my choice to make.
