Totally confused

Hi I have been reading the web site, but to be honest I don't really understand it, so if I may I would like to ask a few questions,I have been on Incapacity benefit for the last 10 years since I broke my back, I aslo get DLA middle allowance, I am going for a medical tomorrow (went once and they sent me home because they were running late )anyway If I understand it right, if they put me on work related benefit, I will get that for 12 months because my national insurance will of been paid in with my incapacity, then it stops ? So do we just have to register self employed and pay it ourselves ? I am totally confused, luckily I can live without the benefit, but I would like a pension eventually, do you have to go to the dole office every two week to sign on if they put you on a job seeker list ?
If this isn't allowed here, can you point me to a forum where I could ask please, Thanks a lot.

As you say, if you are put in the WRAG it will be paid for 365 days on a contributary basis. It would only continue after that if you are entitled to income-related ESA. After that your NI contributions would be credited for your pension as long as you remain classed as unfit for work. You will be subjected to re-assessments during this time, it is expected that this will be in the form of an ESA50, it is not clear whether you would have further 'medicals'.

Thank-you, could you explain what income related esa is please.
