Reboot it using the old name and change the format as needed. It's OK to make money. Do what you gotta do to provide a service people will enjoy. Make a full time business out of it like Joe Meno did if you can. Sell ads, charge for subscriptions, and pay authors and photographers for their contributions. If you need a copy editor I'd be happy to help out with that.
Personally I didn't download RailBricks regularly because I kept forgetting to check for new issues. I'd be happy to pay a reasonable fee to receive a print magazine, as I do with BrickJournal, but online only is probably more financially viable in this day and age.
