Only thing that needs to be done, is the logout button is set to logout of the overall Joomla system, instead of Jomsocial. Honestly though, logout is not necessary on my sites as they auto logout a person after X amount of time anyway, and just adds another button for clutter.
Second thing, I had no idea which to download as there seemed to be 3 alerts/everywhere mods which did roughly the same thing.
None of them worked properly on my site, as all three caused some modules not to display and it messed up the main page. One of them was especially good, u could change the background to transparent. The last one i downloaded (this one) didnt even display.
But this seems to be the only mod with a global logout / PM functionality which is after and i will gladly pay for a working version.
It definetly has potential once the coder fixes the bugs :) Note im using jomsocial 2.4x and joomla 1.7x
Heres hoping things improve.
