I just edited my Profile and there are a bunch of question marks in the section i edited.  This also happened after I edited an entry in the forum a few days ago.  What's causing this?  Is it something I'm doing that I can avoid (I didn't add any ? and when I try to edit them out, it doesn't work). 

Seems to be a systems glitch. It's been around for a couple of weeks, give or take. Don't know if TPTB are working on it, but I believe they know about it.

I thought the ?????? problem had been corrected?  If you copy & paste, ? will appear instead of characters not recognized by the PBS program (Firefox). 

 A few weeks ago ??? were appearing wherever you had double-spaced, but it was fixed last week.  sounds like a recurrence!

It's not fixed.  My bulletin board is riddled with them.

Apparently the double-spacing problem recurred. I took out all double spaces (like at the end of senteces, afer : etc.) and removed double line spacing, and that removed the ??  Thanks, it was mildly annoying.
