A senior member posting this question here? What the fck is YOUR problem ?
Go ask in Pool section, idiot.
It should be altcoin mining section IMO, since "CTM" is most likely an altcoin...

ctm means ConcheTuMadre which means "your mother's pussy" here in Chile and seeing the profanities by OP my guess would be the pool is a Spanish pool.
I live in Chile for 2 years now and only last week realized what this ctm means many chileans use to express excitement.
