thegeeks, bitme, or learnbits

looking for a replacement for docspedia. I need tracker with medical and computer programming related material but mainly medical. if someone could give me an invite to thegeeks, bitme or learnbits i would be grateful. I did have 1.3-1.4 ratio on docspedia other than that I don't have any ratio that I can show since it looks like docspedia hasn't been working for the past few weeks.

Could someone tell me which one would be best thanks
