It's been quite a while since oldunreal had an overhaul, but we are moving to another server which require some updates and changes. The biggest change is the migration of our old reliable YaBB forum to phpBB. This system expects you to login with your username and old password known from YaBB.
If you experience any problems there is also the usual "password forgotten" function. Don't forget to clear your browser cache!
If you have any further concerns feel free to contact me: Smirftsch@oldunreal.com
Actually it will run strangely enough. We tried a bit ago to backport Unreal 2 E3 alpha map back into 227. The old editor can't run it but your client can with some setbacks....
there might have been few crashes here and there though so things had to be simplified on the map. But that's at least my experience. But perhaps I should let someone else speak who might know the exact details.
