Im not sure if i have a legitimate say in this because i hardly post on this forum. But it doesn't mean that i dont keep an eye on it. Every time you have mentioned a "better" server it hasn't been.
Why not use a forum service like proboards ?
-Their new V5 software that came out this year is brilliant, its got full customizability and can change it to how you want it to look and be used.
-Proboards also have Free customer support
-All server management is done by them, all you need to do is take care of is the forum itself and the members
-I have never had a single server problem with proboards in the whole 7 years i have used it!
-The service is completely Free
-Yes, there are ads but they can be taken off for $6 every 50,000 pageveiws. You can even set it so only members of the forum take up the pageveiws and not random guests/bots.
-You can transfer your own domain name (even one that you have already bought) to your proboards forum for a annual fee of $13.99 (thats $1.16 a month)
No brainer in my opinion.... :P
