1) Do not request complete/finished formulations.
The best way to get help on this forum is to show that you actually need help and are not trying to use us to do work for you. With that, if you have an existing formula that isn’t working out, post it and ask for some feedback on your problem. If you don’t have a formula, do some research and try to come up with one yourself first. If it doesn’t work out, then ask for help or feedback.

It has lots of beginner formulations.
Good luck!
