capabilkity for work questionairre recieved

just one final question, do you recommend sending the questionaire back by recorded delivery or should it be ok sending it back in the envelope provided, thanks for all your help, i cannot express how stressful this has been for me, filling in the questionaire is like writing your auto biography,
thanks in advance

just an update, i have not heard anything after returning my questionairre back in february, we are now well in to august, i don't want to contact them and i am still recieving my payments, i c just wanted to know that if the waiting time for a response is usually this long? it is about 6 months since i sent my forms back,
many thanks

hi,
i received a letter this morning regarding my esa application, i phoned them up and they told me i will remain in the support group for another 3 years before it is looked at again, which is a relief, just wanted to know if this decision will effect my pip, which i haven't had to re-apply for yet, will this decision for my esa make it less likely for them to try to take my pip off me, or are the 2 things totally independent?
thanks in advance
