Yes, I sometimes do that, but like I said before, I cannot download the add-on link from vbulletin forums since I do not have a licensed account.
And since I can't dl it, I wouldn't know what type of installing is required and I wouldn't be able to find out if I have the access to the things I need to access for installation.
But, even if I can do it, I'd wait for Entropy's permission before trying anything.
