As others said this is the wrong section, This section is about questions releated to the actual naruto manga/anime. It should have been posted here:

but dont worry about it, its a common mistake and ull get the hang of things soon enough.
as for the question the answer is: No. Im not a really old member so I dont know If people used it in the past but for almost a year now I havent seen anyone use the chakra system, Reasons for that is mostly because battles end way before the chakra of a fighter runs out and also because its restricting and most people would be lazy to calculate it. Also we dont use the healt system either because everybody has too much healt according to that, so to be killed somebody has to be hit with 10 very powerfull attacks that would kill in 1 hit. so it doenst make anysense and besides getting 1 hit on ur opponat is hard enough and the battles would be over 20 pages if we needed to hit opponants like 10 times to finish them off.
Hope it helps.
