I was wondering something similar myself. I have a few New Era things I'd like to publish too. I was wondering what the reaction would be to self-publishing a few things.
We'd be interested in material for any version of Traveller. If nothing else we might have use for it for our Traveller's Aide line. The TNE era will definitely be supported but there will be some revision so you need to run that by Martin. If you are interested in submitting your ideas for consideration, drop an email to travsub @ TravellerRPG.com
