3 Weeks ago, I submitted a run for Final Fight 2 Haggar Normal any% and it has not been verified yet. I was told I had to wait 20 days/ 3 weeks before reporting in.

What should I do? Get in touch with the moderators on social media or someone on SRC?

You should obviously DM the game's moderators first, on- and off-site. If they don't respond after some time, then this is when you submit a Support Hub request.

@Lordofchaos43 hasn't logged in for 3 years, but @Sm_Izumi was last online today. So you probably don't need to request to Support Hub

Okay, gotcha! Thanks for the response, much needed!
