I'm using the "@" in all of my email-addresses (tag EMAIL) and in some of my notes. Following the GEDCOM standard, the "@" has to be duplicated when exporting such records e.g. like
2 EMAIL hermann@@hartenthaler.de
webtrees does not follow the standard at that point. Up to now I never got a problem with that; all importing programs, I used, can read tag EMAIL with only one "@" sign. Several GEDCOM validator programs generate an error message, if there is one @ instead of @@.
Was this ever discussed here and what was the decision?
