Wich forum should I take?

hi guys,
I have a forum for 3 months now,
but I thought it wasn't good enough.So I opened a new one.I really want to know if I should keep this old one or continue editing this one.The language is Dutch,
so you won't understand a thing,
but that doesn't matter.In the first forum I used phpBB,
but the second link is from simple machines forum (like the one from RomUlation).So,
wich one must I keep?Thanks in advance!Ps,
Sorry for my bad english.

Well you should have edited the old one really.If i had my old phpBB adress I'd use that...now that's lost...(and the newer smf revival, no one went :( )

smf is a lot more secure than phpbb.

well I have a problem.
I downloaded a phpbb-smf converter but the problem is I don't know how to convert the posts :/
