I just did a corporate matching for Omni C, I don't think it's possible for sudoroom.
Yes, that is correct. Legally, Sudo Room is a sponsored project of the Omni Commons, so if you want to make a tax deductible donation to Sudo, I think you can only do that through Omni.
Right now it makes much more sense to donate directly to Omni anyway, because if we were to lose the building we'd all be up shit creek...
