I like MyBB but my code was 10 years old and highly modified to the point that I feared MyBB upgrades because everything would break! So I decided to switch to IPB because I am pretty familiar with it from my work forum. I like IPB because it has many of the plugins/apps in the core software so I don't have to add a ton of 3rd party stuff! IPB is great right out of the box!
Nice forum btw...I am a mod at PAFOA.org - Pennsylvania Firearm Owners Assoc. Keep your powder dry, fellow patriots!
