Dam1an thank you dude, you r always looking so fast... ;-)

Functionality-wise? I’ll just bash out some random thoughts (I get a lot of them, so I’ll try to stay on-topic). If it’s not what you wanted, or if you want more information on something specific, I’m sure you’ll let me know.

MPTT to maintain the categories.
Zend_Search_Lucene for indexing posts.
Breadcrumb class for helping users navigate.

Can we use Zend_search_lucene in CI?
Is there any library/class that can be help ful? also i am using jquery in my site so is there any thing on which i can apply jquery in forum so that i maintain style for my site?
