Submit articles from the front works, but how will users be able to edit the published texts from the front? I would want to have a link for each user so that they come to all of their own articles and to edit and delete articles. Is it possible?

I do not use K2 User for it does not work with Jomsocial.

Thanks in advance!

One you have front end editing set up, if a use has rites and views an article he has rites to ther e will be an edit item button added

Thanks for the reply! Yes, it works well for new items. But we have about 300 user and each has hundreds of articles. They need to quickly find their own articles, edit and delete.

I have the latest versions of both Joomla and K2.

Only think i can think of is to give them limited backend access

Thanks for the reply, but there is no option to give novice writers back-end rights. I wish something like this:
