I have a JAR licence (I'm instructing on a Middle Eastern licence) and I did actually renew my ME/IR in November and completed the EASA form as suggested - for reasons unbeknown to myself I didn't renew my SEP whilst I was there! (To be honest I didn't think I'd need my SEP as I'm now trying to get into the airlines and also I couldn't afford the extra cost)
Regarding the revalidation by experience I was referring to the period between 2010 and 2012.
In fact I may now wait until the summer, as my FI has lapsed - which means I'll have the flight test and seminar to attend - so hopefully I can kill two birds with one stone!
