Hi Simon
Welcome to the forum. I hope you'll enjoy sharing music with the other members. Without seeing/ hearing what you've done, I would say only this: take special care and attention over your presentation. If you plan to send a home-recorded cd in a case with your name written in biro, then don't.
Make sure both the disk and the case contain the following information: name, address, phone number, email. Make sure they look smart. If you've got an eye for design, even better. At the very least use your home printer.
Let us know how you get on
