IMO it'd be interesting if there was some kind of ongoing thread of different spells the members could try, to see which ones yield the best results for most. I got the idea from reading 'The complete book of spells, ceremonies, and magic' by Migene González-Wippler, which is full of spells and some of them are quite simple indeed. I was specifically thinking of spells that most people can perform, with not too exotic ingredients.
This happens to be something I'm interested atm, but I'm sure there are others who are also into folk magic, hoodoo etc. Anyone interested...?
