I hope to set some records when I have the time and equipment.

Just wondering a few things like how to use speedrunlive.com? And how to post a run here?

Define “using SRL”. If you’re talking about racing, you’re better off reading the guides to racing on SRL itself. Racing is all done through IRC, so you’ll need to make sure you understand how to use it.

And to post a run here, you go to the game you want to submit a run for and click on the “Submit Run” button in the top right corner of the LB.
