Tapping “Follow” or “One Time” donate does NOT result in a recurring monthly subscription. Please follow these steps: * Create your free Ko-fi account (you need an account so Ko-fi will know to unlock subscriber content when you visit my page) * Tap "Support" * Tap "Monthly" (amount is automatically set at $25) * Tap "Donate" (even though Ko-fi has the subscription option I haven't been able to find a way to edit the button that says "donate" to say "subscribe") * That will set you up to auto-pay $25 per month via PayPal. You should receive an e-mail from PayPal that can serve as a receipt or log onto your PayPal account and print what you need from there. * You will receive an email from Ko-fi when I post new content. When you are on the site you'll also see a Ko-fi notification (🔔). I will also be posting announcements about new content on social media (Facebook, Instagram, Twitter) and my blog (which also has a way to subscribe to e-mail notifications) **** Here is the direct link to the post with the Feature Matching charts (only accessible to recurring monthly subscribers): https://ko-fi.com/post/Links-to-posts-about-most-current-feature-matching-F1F5C9DMD ** I'm a pediatric Speech Language Pathologist with over 30 years experience in AAC (augmentative and alternative communication) and founder of OMazing Kids.
