I've had the same issue as posted below with having to wait multiple days for a new account to be able to post in BuySell.
Now I'm through that (+4 days) I get a new error when I try to create an ad saying 'since this is your first BuySell post, we need to verify your account and you will receive an email etc'
I already verified my email during the sign up process, this is confirmed when I click on the original link which says 'email already verified', but i still cannot post an ad.
Is there anyone who can look into this, or shall I just delete my profile and start the sign up all over again?
Same thing happened to me today, trying to list an ad for the first time. Registered a while a ago and have been able to post in the forums. Not seeing any verification emails either. NVM, email came through.
