Dhrup built a roles system for me, maybe you could give him a shout, I am sure he could tell you what is involved, I can say this, it wasn't cheap but it works like a charm :)

Letting users register as admin?  That sounds like a terrible idea...

Anyway, if you're looking to wrap stuff up for a specific username:

if (elgg_is_logged_in() && elgg_get_logged_in_user_entity()->username == 'myusername') {

  // stuff I'm allowed to do but noone else

}

Thanks i will insert it.

Hello tested the code but did not work. I inserted it in actions/admin/user/ban.php but nothing happened.

I'm using elgg 1.7.8

I tried this too
if ($_SESSION['user']->username == "admin") {

// stuff I'm allowed to do but
noone else
}

oh, yeah that wouldn't work for 1.7 because the function names changed.  Honestly I haven't worked on 1.7 in so long I forget what the exact function names were.  Consult the docs.

Also, 1.7.8 is way old.  At least upgrade to the latest version of 1.7 for some important security fixes.

Thanks i will do just that

Thanks i will do just that

I checked the doc but still not working for me.
Pls where exactly in elgg 1.8 did you see this piece of code so i can check it in elgg 1.7
