Hey tc566,
If you're talking about our own Steam profile forum addon here, well, it's quite buggy.
I'm still not entirely sure why it works for some and doesn't for others.
Maybe check to see if your Steam privacy settings are set to Public?
The forum software we're using is quite old now, so it was never intended to work with Steam integration. I still wish some day to upgrade to newer software, with real Steam integration.
For now however, don't worry about it. That's why we added a separate Forum field for SteamID. You can add your SteamID there, under Profile > Forum Profile > Donor SteamID.
No it's not private, I check it online all the time.
I thought the other one is for donors only, anyway, I filled both of them.
Thanks for the help.
