Edit: I tried again: I can Preview, but can't create a topic on the Electrum board.
This is interesting because, with the preview option, you still make some kind of entry in the forum database. It can be said that you still have editor access to the forum.
If everything is up to date as suggested earlier by other members, maybe you should also check your internet connection. Are you perhaps via VPN? Is the current IP address you are using perhaps blacklisted due to spam or similar?
Why use TOR at the first place anyway? Can't you use normally?
What is normal? Who defines the term normal use of the Bitcointalk forum, You?
Why do you think that everyone should access the forum the way you do?
Yeah having privacy is important, I don't deny it. But for some people, they just don't care.
While some people care
