A different way of doing the same thing is to give that person a unique email to send to which is routed both to your regular email address and to the cell phone. I have done this with a number of email addresses. In essence instead of being a mailbox, the address is a mailing list which is forwarded to any email addresses you wish.
One example is email from my ISP or financial institutions are routed both to my Eudora email client but also to a Yahoo email address so I have access to it in case my computer crashes or is otherwise compromised.
It looks like your newsreader screws up < > links too, by being obsessive about line lengths. Newsreaders should /not/ break such links into multiple lines, even if it means the line length is too long - it's okay if the link wanders off beyond the right-hand margin when you read the post (unlike normal text, which should have limited line length).
So unless you can change Pan's settings to fix this, or you change your newsreader (which would seem a drastic solution), then you are probably going to have to keep adding a "watch the wrap" note to long links.
makes a difference in some software and makes no difference at all in other software.
Some software lets you post long lines, some doesn't, but the software that treats as special and otherwise breaks long lines has one bad effect. every time spmeone posts a broken link one of the users of such sofware will blindly proclaim as the solution regardless of wether it actually helps or not.
I knew that some of the older text-based unix newsreaders do not support < > links, but I thought most others did. Although it is not (AFAIK) part of any official RFC, it has become a common de-facto standard - and I think it is fair to guess that the substantial majority of Usenet posters use a client that supports it. So unless I know otherwise (and now I do, in the case of Pan), I assume that a random poster's newsclient supports it, and that the poster merely forgot (or was unaware of < > links).
Does slrn work with < > links?
Indeed it could. But it could be a long wait, unless Joe wants to do it himself.
