Just thought i'd let you guys know about somewhat of an exploit i found. Last night i jumped from level 4 to 5 (10000xp) in 19 mins. Here's the trick:

Look thought the cargo transport missions at the station and look for the ones that say... We need you to bring us # of blah blah from whatever station and bring it back here. You will get a bonus for fast delivery. Lets say the mission is to get 5 ferric ore and bring it back. Accept the mission and go ahead and buy 5 ferric ore from the station your at. Step outside and come right back in... mission complete. Oh yeah, and you get reimbursed for what you just bought :) Would you like to sign up for more work? 1 for yes of course.... Bring us 6 food crates from so and so.... buy 6 food crates and step outside again. Too easy. Only drawback to this is you will have to abort missions to get new ones because not all will be the mission you need to do this and you will lose faction. But out of the 19000xp i made last night, i only lost about 100 faction.

yes, this is a known bug,

2 items however.

item 1. please do not post exploitable bugs where everyone can see them.
use the bug reporter on the left or the one that downloaded with your client.

item 2. good work, thats what we are here for.

Sorry, didn't think it would matter in a beta version otherwise i would have sent an email :)

Another disadvantage is that after trade 5 you almost never get those kind of missions anymore.
