SMF is going through some updates and their new version has a mobile friendly default theme. They released a companion mod that edits the old default theme to make it more responsive which I just patched to the custom theme this forum uses real quick.
Let me know if some pages/functionality break because of this. Note that it's not a very good mobile theme because as I understand it it was mostly added for google/seo related reasons.
I also deleted all steam-only members with 0 posts. Has no effect other than their settings/registration dates and the member count because if they ever do revisit the site they will use steam to log in and it will create their account again anyway.
Reminder: If you already have an account on here with an email/password don't use steam login unless you've linked it to your account (pic). Otherwise, you'll end up creating a separate account.
