As someone who is actively learning ASL, I will take those resources, yes. Please and thank you.
I also want to add that manual dexterity isnβt the only thing that affects signing. The signing area is (roughly) from forehead to waist and from shoulder to shoulder, and the location, rotation, and movement of your hands are all important. If you canβt lift your arms above a certain level, reach across your body, or have some other problem with your range of motion, youβre going to struggle with ASL.
Also, your face is surprisingly important! The shape of your mouth and the location of your eyebrows (raised, furrowed, etc) are used to convey a lot of information that is normally communicated through things like pitch and tone in spoken language. So anything that impacts your facial control, or even just wearing a mask in public, is also going to impact your ability to communicate clearly.
That being said, I would argue that thereβs no reason not to learn any language, even if you canβt produce it yourself. People tend to look at language learning through the lens of communicating their thoughts, but you can learn because you want to understand other people, too. I think people tend to overlook how much just being understood might mean to their conversation partner, especially if that person is used to doing all the work for communication.
