For those users that maybe previously used the Zumoforum you either have found or will find that the forum is off line and will most likely stay that way. The owner wanted to "retire" and wash his hands of the forum "business", to that end was wanting to sell the domain name and database........didn't happen so at this point it is dead..
BUT, there is now a new forum up and on-line. The database is growing as it had to start from scratch. It is located here:
