It seems that big parts of the FireBoard community has put their love on the www.Kunena.com
forum, which takes over from FireBoard.
As a 1.5 native version that lowers the database load to 10-12% of Fireboard, a LOT of fireboards will switch and it's several versions of Fireboard since Sakic's file got too old to use for SefAdvance.
I know there has been a lot of talk about how 3rd party components cannot be supported by Sakic himself, which is most understable, but from my point of view, at least the "huge" components like FireBoard, CB etc. are so wide spread and used on so many sites, that I would find it reasonable for Sakic to adapt SefAdvance for these.
Afterall, it's also in the interest of SefAdvance (as a commercial / paid component) to stay up to date and not rely on other people to make 3rd party extensions for SefAdvance - who and why would they spend time on that - they do it for free stuff like SH404sef?
So: I would kindly ask Sakic to develope and maintain a plugin for Kunena / SefAdvanced.
