is there a post/message approval option?

There's no option for that on Lefora.

And if you wanted to do this to protect by spammers, lefora has you covered as we automatically detect spam.

I also change your subject from 'urgent help needed' to a more appropriate title, this way it can be useful to other admins browsing the support forum.  We process all support questions in a timely manner, adding urgent to the title doesnt' speed up the process.
