So heres a few pointers for things that can be done to advance a plot.
1. Emote posts. If you're investigating a certain area, or reading particular books in the library why not mention it in one of the IC forums. The DM may PM you some new information, or let you know the next time they see you online.
2. PM the DM. In a similar way why not PM the DM what your character does, or who they speak to. The DM may PM you some new information, or let you know the next time they see you online.
3. Send a message on the DM channel asking if you can RP out the investigation. If the DM is online they'll usually be more than happy to RP through the investigation including any necessary rolls.
Hopefully these are some good pointers. Feel free to ask any questions here
