Be warned: MAMBO is a very nice and "verynice-to-use-admin-UI" content management system I didn't write about so far, altough used it.

It's definately worth a look… and you tend to start playing with tons of nice skins, templates, plugins that are out there and can be installed in a second !

If the big CMSes are too big and the small ones (like Movable Type or Textpattern, both more blogging software but capable to run my company site) are too small for you, take a look at Mambo. Your non-techie users will love it. Extension installation works in second – no zip/tar/root mumbo-jumbo – just some click and install (and UNinstall afterwards!)

For Mambo there is

• MamboForge a sourceForge clone just for all the extensions, language and template packs and other cool extras like even e-commerce/shop modules for Mambo
• hundreds of Mambo templates and a good tutorial on Mambo Template building
• of course a CMS testdrive possible

  For the search engine optimizers,

there are TWO options as I know as of yesterday to rewrite URLs

in addition to the quite basic Url Rewriting features of Mambo

• a Paid Plugin called SEF Advance – that's actually one plugin developed by one of the Mambo Core developers … and a lot of discussion arised because people think that feature should be in there for free as well…
• a free SEF Plugin for Mambo that's released opensource and does MUCH MUCH more than just creating nice URLs for mambo for free…

OpenSEF offers more than SEF - it's an answer to some of the ultra-high CMS requirements I setup myself half a year ago:

• Rewrites all URLs inside content items for seamless site navigation using "pretty URLs" – well of course I don't want to re-edit content, that's not available with the other SEF solutions
• Output all site URLs as either relative or absolute depending on a configuration parameter. (Mambo by default outputs all URLs as absolute only )

Finally some Multi-site option in Mambo:

• possibility for running multiple sites off one Mambo installation (yes, even on different domains, and without core hacks)
• with the possibility to override Mambo's frontend language, locale, title, and some misc settings on a site-by-site basis.

(phew… have to take a look at Mambo again now…)

Nice convenience features:

• install and uninstall using Mambo's standard component management facilities; no need to manually replace files!
• does not require modifications to any Mambo core files – hence no hacks and hassles
• Easily publish/unpublish aliases with the click of a button.
• Export alias database either as a human-readable text file or an SQL table dump.
• Validation feature to check for broken target URL redirections.

for Mambo-Lovers or Mambo vs. DruPal undecisives, also be sure to checkout the very interesting article on Xanaeon that explains their migration from Mambo to DruPal which goes into great detailled insights about both architectures… just what a tech reviewer loves to read. And those guys are the ones that built OpenSEF for Mambo , so they definately know what they are talking about and probably love good software architecture just like me.
