• phpBB: with a large and highly customisable set of key features, it already created lots of communities.
• LiteBulletin: source-based on MyBB, this software has improved with vBulletin's main features.. and it sure is great, and free.

Website software
The best website software available
• Drupal - Drupal is a very powerful CMS. Like Wordpress Drupal has many themes and plugins available. I would highly recommend Drupal!
• Joomla! - Jommla! is one of the best know CMSs around. With a huge fanbase support is easy to get.

Blog software
Blogging softwares are here.
• WordPress - Though it isn't technically a CMS many people use it as one. With many plugins and themes Wordpress is a great CMS script.

I'm not the best at giving reviews. Alright I suck at it. But I figured I could post one. These are all my opinions of these CMSs.


Content Management Systems
The Best CMSs around.

• WordPress - Though it isn't technically a CMS many people use it as one. With many plugins and themes Wordpress is a great CMS script.

Please keep contributing to the best resource thread ever ^^

Thanks for the info, im gonna try LiteBulletin.

If you like MyBB, then you will like this LiteBulletin's version. The ACP is the same as MyBB, but the LiteSoft Group says that in the next version they'll be updating the ACP and many other things you can see in the new category of LiteBuleltin 1.2 previews.
Anyway, yeah it's a modified copy of MyBB with vBulletin main features.

But yeah, it's nice.

Im liking, I feel said for kinds leaving myBB but I like vB More soo.

Yeah.. I feel the same way. MyBB was hard to make.. then, someone pick a copy of it and modify it to a vBulletin free copy. It's like "aww damn, I can't leave MyBB". It's really frustating..

I decided to stay with MyBB. LiteBulletin is still in BETA phase.. maybe when a final version is released I'll try it.

I guess ill do the same.

Off Topic: Did you get my PM on myBB?

Yeah I did. But I have to go now. We'll talk tomorrow.
