You don't have to quit one to post at the other. A lot of people post at more
than one message board. Maners post on Mania, and those from Mania post
in the Mane. There is also BroncosFreak, whose members also belong to one
or more of the others.
Our Admin, Tned, still posts on Mania, and he has already announced his
intention to keep on doing it.
I personally believe we have a better board, and it is going to get even better
as it develops and accumulates more members. But that doesn't mean it is the
only one.
Just go with your heart. No one here or there (hopefully) is going to judge you
for that.
