good people, you are already part of a group of writers who would like to up their game and help others up their game.
you don't need permission, just go ahead and get cracking. have a look at some of the old workshop threads, you should find some really good pointers and opinions on giving
feedback and critique in an honest non-abusive way, seek out those who know their shit and ask for help, most don't bite ...dunno about that Case fellow though
one of the possible actions which can be preformed on this site is if you click on a poets profile you can click on 'comments made' by the poet. so essentially you can read their critiques without even bothering them. I must confess to have done that a lot and totally recommend it
on that note, there seems to be a bit of a contradiction going on here
anyhow, best o luck with the endevours http://deepundergroundpoetry.com/forum/workshop/read/692/ http://deepundergroundpoetry.com/forum/workshop/read/5401/ http://deepundergroundpoetry.com/forum/workshop/read/3000/
