Erm, I hope it doesn't count as advertisement and it won't trigger enrage on mods (if the post breaks any rules - delete pls).
But, for all those who are late to the raiding party, stuck in the "need experience to experience raids" loop, I'd like to bring to your attention the Raid Training Initiative http://rti.enjin.com/
Basically, it's a non-rep hub guild for those who want to start raiding but can't because Eternal over 9000LI in LFGs nowadays (and I can add from experience it's really hard for find a raid teaching guild on EU).
Tbh I am surprised it took us so long to get this thing going, NA afaik had the same thing running for months.
The main advantages I see are that:
1. You are starting in a mix of new, semi-experienced and experienced players, so no one will shout at you/instakick you because of your mistakes, but you have people to learn from.
2. Their event schedule with the current sign-up system seems to be pretty effective in reducing another main problem - getting 9 other people for a raid.
To be frank, I suspect there is some potential in collaboration... cooperation... (my engrish, what it the correct word?) between communities like theopencommunity and guilds like these.
Apparently they also will be happy to welcome any mentors/experienced players willing to teach.
