I'm transitioning my online accounts to a new email address, however speedrun.com does not have an ability to change email in-site. I emailed both support@speedrun.com and contact@speedrun.com days ago and I've received no response. I would appreciate some help with this, thanks.

as with all things, have patience, they'll get to it - don't worry.

Done! Sorry about the delay. The e-mails really pile up :P
