Long time lurker, first time poster - Great forum!
I passed my CCNA in 2003 (No specific track back then), then completed the CCNP soon afterwards... managed to renew them for a while then work commitments got in the way and everything expired in Sept 2014 

Currently on the road to recovery, renewed my CCNA R&S in December, just passed CCNP SWITCH this morning, looking to book ROUTE in for end of March hopefully. Then I can get TSHOOT done and get back to where I was before!
If I can give anyone any advice, it's once you pass these exams, keep on top of them. Having to renew everything is such a chore 

As a contractor now, can't afford to let these things slip in future!!
