Honestly, this sub-forum should just be locked and we should just use the other sub-forums for anything pertaining to R&D. The most reasonable one would be the Unstable sub-forum, as that serves a somewhat similar purpose to R&D.
Also, fun fact: Ampersand (this thing -> &) isn't a symbol. Its actually an English letter, that is used exclusively to mean "and". There is also Thorn (lowercase "þ", uppercase "Þ"), which was used instead of "th". Eth (lowercase "ð", uppercase "Ð") is also an English letter. The most infamous English letter is the "long s" ("ſ"), whose complicated rules were quite ridiculous. To quote Wikipedia:
It replaced a single s, or the first in a double s, at the beginning or in the middle of a word (e.g. "ſinfulneſs" for "sinfulness" and "ſucceſsful" for "successful").
