Am not sure how this may be helpful to Jr members and all newbies yet, because I don't think I have grown enough in this forum to know much to say or do.
No knowledge is a waste; it can also be useful for you if you want to learn how to copy a signature. You never can tell if the need for it will arise in the future, shuffling the bounty side. I think I have come across campaigns that also made available signature codes for junior members, but they are always very small since that's what the rank can take in.
They are downplaying the information shared by OP while the fact is this is helpful for all people in this forum especially for those people who use mobile to access Bitcointalk especially when they are away from their PC.
Also he better go somewhere else if he don't need this information since for sure later on he want to find good guides that can help make his life more easier especially when he try to do something like wearing signature while using his phone.
BTW thank you for sharing this information OP, although its complicated option but for sure its still helpful.
