Hello

I cant join the test server by : test:Solitary and then my password, read the wiki, i should be able to join it,
i tried to change passwords but that dint work out.

so can anyone help me out?

The test server player database is not automatically synced with the production server database, so you will have to wait until the next sync (it could take a while).

ah but im playing this game for like 3 months now.. so i think it should be synched :P

Solitary, not sure when the last sync was and I suspect it's a manual sync. If it's like github then it could take some time to update it.

Members of the PCC are automatically synched. Everyone else isn't. So, yes, it could be awhile.
