The first question that pops in my head is why are all the icons like.. stripped from the forum? I see none for some reason.
As for editing your posts, check the permissions to see if it's something there. You may have to look in both the Administrator group and Registered Users group as well to find out what's going on.
And as for the second thing, the email is because of their junk email filter, so you can't do anything about it. You'll have to tell them to allow whatever domain your sending the email from through their filters and such. That's not a forum issue at all really.
No longer supporting phpBB. PM or email me regarding support and you will be ignored. I'm fully done with phpBB and everything.
