I’ve written a small guide to ELR on Wikivapia (no longer functional - use http://e-liquid-recipes.com/guide now).
Wikivapia is a project started by the cool guys on www.reddit.com/r/ecr_eu - If you feel you can contribute information to a vaping wiki like that, I highly recommend you register there!
My guide is here: http://e-liquid-recipes.com/guide
Can you guys think of anything I missed, or anything I need to expand on, rephrase? Do tell, or even edit the page yourself!
