The server is up with the new boosts! Download sounds to hear them. The purpose of the boosts is to prevent people from falling too far behind, so you can now catch up even after a crash. There is one problem I haven't fixed yet though- if you use a boost while going off a ramp, you might go so high that you fly over and miss a checkpoint. Currently, the only way to know that you missed a checkpoint is to recognize that your checkpoint notifications stop appearing even when you pass through checkpoints. An alert for this will probably be added later. The boosts will not be part of the gamemode, and they will be removed from the server tomorrow.
I have class starting tuesday (8am to 10:30am every day), and an internship after that every day, so I will be less active for several months.
