Extensions on mental

Hi all,

I set up my Radiant install using the gem (6.2) and following that I
joined mental branch by using

|rake radiant:freeze:edge
||rake radiant:update|
(and then running)
|rake production db:migrate|

I’m trying to run extensions on mental branch now and I have installed
three into /radapp/vendor/extensions - thing is none of them are showing
in my admin? I have radiant mental in the vendor directory but the
sym_link is from ~/radapp/public. I’ve also run the rake command -rake
db:migrate:extensions -from the /radapp directory after installing each
extension.

Does this all sound correct - I’m a newbie to mental so help would be
appreciated!

Thanks.
