using userspice to login to multiple platforms

[luigi7890]

Your english is great.  

So obviously it matters what the other platforms require to login, but there is a script in usersc/scripts/custom_login_script.php that does things automatically when your person logs in (I just made a better script file that I can point you to after we do the next update, but this will work).  
So whatever you do in that script will happen when the user logs in, so that is your starting point.

The question I have for you is are all these other applications on the same server?

Thanks for your immediate reply. Yes, these applications are installed on the same server, of course each on a different folder. It's a testing installation so I can play with it as much as necessary. My site is hosted on A2Hosting and I manage it by CPanel, installing the software with the help of Softaculous.
