50 seems perhaps a little short? Many of us like to use a link in our signature, and guessing a lot of those broke. I noticed mine did.
Not sure what I had before, and noticed it truncated mine to 40 characters even though 50 is allowed. I noticed John’s links still show up, but I couldn’t figure out how to include a link in m sig because typical code requires the link as well as the text to the link, so 50 would hardly ever be enough, so I just deleted it for now.
It seems arbitrary as well, example I noticed Mark Segals was truncated and useful information is not there, but BobShaw is definitely more than 50 characters and appears in tact.
Not sure what the difference is.
