Also started in my realm on 4/28/22. So far, I have been able to use /w as well as /say, but /me did not work. (And friends and I are too new at this to know how they can message me back.) All new signs have letters disappear immediately, but as far as the small number of signs WITH text, some are newer, but some have been in place for at least a couple of months, since we started the realm. Can't find any pattern as to which ones retained their text vs not. Also noted that so far, looks like the same signs are blank (or in a few cases, with intact text) for all players, regardless of who placed the sign or when it was first placed.
