Thanks guys! I am of course planning to level *at least* one character up to level 50, possibly more over time. I have 6 level-capped characters on another MMO, as an example, so this is a familiar routine. So I can always supply funding from the main toon to the craft mules, until such time as I start to level them up as well. I picked level 10 as my sample level since I would get at least each class into the Republic Fleet, off the starter world, to ensure they got a companion and crew skills trained. Getting a 2nd companion at slightly higher levels, once they got their personal ship, would also be smart. I mostly wanted to check whether there were level requirements for crafting, and it appears not. Thanks for the advice, and especially for the solo crafting guide!

I'm interested to see whether it's possible to have multiple characters, all on the same account and same server, each with a different crafting profession. My idea is to get each character to at least level 10 so they get companions and crew skills, and then level each one's crafting skills to 400 so they can mail crafted gear around between characters. This way I can self-supply myself with all required items; lightsabers, armour, stims, medpacks, etc. Is there any issue with scaling craft levels to 400, while the character level itself stays ~10 or so? I am just wondering if the missions can all be done at low character levels, or whether the high-end missions to gather new materials need to be done by high-level characters?
