I have just recently changed the server this forum is hosted on. Thus, in the time it takes for the domain’s nameserver change to propagate (up to 48 hours), you may be visiting the forum on the old server, and posts you made there will not show up on this new server.
But no worries. You can just post your topic again, or wait at least 48 hours after this notice before posting anything new.
Update: I am currently optimising the site, both on the server’s end as well as on the delivery network end. I you notice any issue, please let me know.
PS: If you’re seeing this notice, it means you’re visiting the forum hosted on the new server.
