In the same time, when an event is submitted by a user, is it possible to add in ADMIN notification email, the category linked to the event submitted ?

{CATEGORY} for category - I'll have a think about the email address

ok works fine for CATEGORY thank you :-)

regarding email, could be very helpful because ADMIN cannot contact user if needed.
only the login is displayed :-/

change line 279 of administrator/components/com_jevents/libraries/saveIcalEvent.php from

$created_by = $user->name;

to

$created_by = $user->name . " (".$user->email.")";

wonderful works fine <!-- s;-) --><img src="{SMILIES_PATH}/icon_e_wink.gif" alt=";-)" title="Wink" /><!-- s;-) -->

many thanks !

Last question, you will integrate this code update on next release or I will have to backup and restore this files after next updates in the future?

I've already coded it in for the next release

perfect and thank you again again :-)
