If your OH is not working full time, and you are seeking to reenter the work force...sign on. Even if you only get €5 a week, even if it means engagement and signing jobseeking compacts, not doing so locks you out of training. In theorey, if a course is not filled with those on the live register, places can be made available with no allowance to people such as yourself. However the reality is courses are almost always filled from the live register.
You can of course do ecollege and Springboard as a paying participant.
