The database won't go anywhere. It just requires a new mysql module, which he can just ask me for, as im using it for OCRP2.
Other than that, hes not started porting HL2RP yet. Tho he probably should if he plans to have it ready anywhere close to the 24th, which is when GMod 13 is scheduled to be released. Unless Garry gets upset and changes it to the 24th October because he had to take 2 weeks off to Egypt. Oh and porting HL2RP is a bit more work than just changing datastream to the new net library.
