Pinmental do you get something when someone signs-up through that link?
As of now, no. Though CCP has hinted that they are tracking who "recruits" who into DUST 514, with the recruitment links. So as the above poster said, probably, at a later date.
Anyway, rules-wise, you should be fine putting the link in your signature (your own link, that is).
