1. Do not post multiple times in a row, there's an edit option for a reason when you need to and in this case your just being stupidly impatient.
2. There are probably no force users on Gand and posting in here won't help you, finding someone to test you is an IC action and this forum is for OOC Questions.
3. Any force user who is able to and has trained the Force Detect skill can test you, these are only other players not NPC's. Finding one who will test you can be difficult, usually it can only be achieved by personal contacts. Your best bet is to assume your not force sensitive (as you probably aren't) until the opportunity arises, when you join a faction they may be able to organise a force test for you at some point.
Just to reiterate: Few force users test people who appear in SWC requesting force tests and it's very unlikely your force sensitive anyway.
4. Ignore Vega, going to Imperial Center will probably get you killed if theres anyone around to do so and Vodo does not test random aliens. Whilst Raiden could be technically correct, I'm 99.999999% sure there isn't a force user in the same city as you.
