There is no hosting account associated with the forum account you are posting from.
Further more signups have been closed for little over a year now, so if you had a signup process going it would be at least that long ago it started so likely it was halted due to our maintenance that started in late December 2019 which also had the signups turned off.
There would be no actual account to login to based on that information, as it was never fully created likely due to unconfirmed email address. If you feel this is wrong we'd need some more information to look into it, email address used for signing up would be the best bet in order to find anything.
