Thank you for contacting us!
You are more than welcome to provide us critical feedback, and also suggest other improvements you would like to see @ Ramdoot. Note that this work is in progress, so you will see that many courses are incomplete, or only have a start-page with no content - please bear with us before you comment about these pages. We have our day-jobs that pays - so we only work on this site when we find time. We are still managing to keep it running by dedicating enormous weekend hours, and we ensure that these pages will slowly come to life.
Please do not spam: we are a bunch of volunteers working to keep this running. Any spams will only bring our spirits down and make it difficult for us to continue to provide FREE courses and articles.
