Could you go to admin panel and take away the waiting for 7 days before i post an external link ( it will all be youtube! )
The limit to the avatar picture is pretty small... this can also be changed in the admin panel.
I havent tried but i think non staff can post threads on news and updates which should strictly be for admin so change that in a panel as well.
If you want to change your domain for free, search up co.nr on google and there will be a link to that enables you to change your site link to ( url ).co.nr for free so only if you want to change it or shorten it...
Dont hate!
