> where can I propose some patches and bug fix for tikiwiki 1.9.7 or later ?!
Hi leelouch, and Welcome to Tikiwiki community!
Plain users (not coders) normally post bug reports or requests of feature enhancements (RFE) at:
Coders (bug fixers, RFE coders, creative coders , ...) communicate through tikiwiki-devel list (look for it, if needed, at http://sf.net/projects/tikiwiki ), plus on IRC channel #tikiwiki (ConnectingToIrc), and they directly commit changes to code at cvs (http://dev.tikiwiki.org/CvsTips)
Hope this helps...
