[development] Assigning user to roles programatically

That is the caveat: I did not do it at user signup time, but rather
as to assign the user to a role when certain conditions are met.

I vaguely remember two modules: one to assign the user a role
automatically at signup, and another to assign them to a pre-defined
"in limbo" role (something between authenticated user and anonymous
user). The idea is to keep them in this role before they are given
full privilege so as to weed out the trolls.

Can't remember the names though, and my PC is too slow for me
to check it.
