I did figure it out.. I used [musername] instead of [username] to show the color.. I took the "m" out and all works now.
can it be allowed to mods/smods without the rest? I mean give them the option rather than doing it via admincp
Thanks
EDIT:Wow ... I added a link to another admin and I was able to switch to his account without asking me for his password.. I don't even know his password !!!
Thats rather not good
EDIT: I noticed theres no drop down in vBPortal .. also, there is a drop down in vBAdvanced but it lists no linked users
