A good site for tutorials, custom sprays, programs, and generally everything to do with making/getting sprays is
www.edit-strike.nl and you need to bind a key to "impulse 201" to use sprays in ESF.
Another good feature of this site is the forums. You can go there and request custom sprays to be made, which are
usually done within the first few days, therefore not requiring you to learn how to make them yourself.:]
