Hi Im new to moodle,i wanted to group the users to perform some activities within groups.so first i enabled groups in miscellaneous/experimental (and then in moodle docs they have told groups icon will be displayed in course administrator) but i did not find that icon.but groups folder is available inside moodle installation.can anybody help me in that. manually if i go to that url its working fine...but how can i get that groups link in front end????

Can anyone help me how to proceed in Moodle...how easily we can modify the existing code and how can we add new pages in moodle????
