Can i use the same user (wallet adr)  for different servers?

Hi..

i'm mining with my 6 servers (CPU) ion your pool...but i have this problem,

All servers seems to be working fine but in your poool page http://5.9.213.199:9372/static/p2pool-node-status/ i do not find my wall with realtive has rate while, if i try to mining wiht gpu from home, my  wallet address appear..is it normal?

However i receive the coin in my wallet, so, i think that my miner stay working....i hope

thank's for your job
