A warm welcome to PF!
As said above, don't forget exploring the newly-created DIY forum.
Just to make sure we can help you as much as possible, make sure you know about the three main sections in PF:
1. The main forums, that you see in the first page.
2. Insights Blog, available at the top row (header section). It contains articles that help in learning topics to a great extent.
3. The videos, also available in the header section. The media gallery now has some great videos in almost every aspect in science, and they provide an audio-visual learning experience.
I assure you that you will have a great time here.
With regards,
Wrichik.
