Hi everyone.
I'd like to know if someone can help me. I need that when someone receives a private message it'll be notified per mail.

I use XOOPS 2.3 and have the private messages module installed.

Yeah - that would be a good enhancement for the PM module that ships with the XOOPS core.

There is an alternative to the PM module.... try Lord Vernom's mpmanager which is now at v2.74 and has been coded for XOOPS 2.3.x - it is much more fully featured than the PM module and is more like a webmail service where your users can send files, etc to each other.

See this News item:

The there is a link to v2.74 in a comment-post by LV himself

You'll need to deactivate/uninstall the PM module before installing mpmanager

I installed the improved module for private messages "MP Manager", but I'd like your help to know how to add it on the XOOPS nucleus so as if it were the "PM" module and that each time a reference to sending a private message, this "MP Manager" module opens up.
