Hi, welcome on this forum where users try to help other users.
I want to help you, but please specify more your question. You are in which view, what do you want to do....

Hi, thank You so much foto help. I Need that 5 people Can modify event I created from frontend. I create 5 users and a group in Joomla, i create a new level access only for this group. The problem is that in frontend i can t see edit button .

ok, what is your language? google translate is horror!
if you know this 5 persons who should be allowed to edit an event, you create a JEM group and associate the croup to the category with the event inside. then go to the settings and give permission to edit events.

Maybe I can relate to this question: there is a confusion concerning the access rights in JEM, since there are access settings in Components > JEM > Settings > User control AND there are settings in System > General settings > JEM
The first settings are old and don't seem to be used anymore. In stead you should use the Joomla ACL settings where you can create user groups and specify settings for each group. This is in some way more fine grained taking different user groups into account. The settings in JEM are legacy and based on the predefined Joomla 1.5 user groups.

Here's what you should do:
So if you want to have 5 people edit all events, create a new user group and call it something like "event editors" or "frontend event admins". Make it a child of registered users, if it's the only thing you want users to in the front end.
Add each user you want to have edit rights to this group.
Then go to System > General settings > JEM and allow the group to edit all events.

Note: it is not possible to have multiple users edit just one (same) event. It is either: edit own or edit all.

@Jojo12: the general settings are not as fine grained as the old JEM settings concerning what a user group can an d can not do. I can not make a distinction between editing an event and editing a venue. I would like to allow a registered user to add an event without having the admin approve it, but I want the admin to approve new and edited venues before they are published. (Users don't always check wether a venue already exists or add venues that are not allowed.)
