I really like the IF abbreviation, having thought a lot about ifs (conditionals: real subtle creatures, much involved in all we humans believe).
As to the geeky side of things: I very much like quite a few of your posts, for you dug up some great findings. Here is one you probably know, which I like, because I think professor Malcolm Hooper is one of the most sensible, rational and informed persons writing on ME, and everybody with ME owes him a lot:
Re smilies: Yes.... same here. I like them here better than elsewhere (I know them best from programmers' forums), and I think we owe that, like many things on the forum, to Kim.
Re the heart: Here I can't get your meaning precisely. It's simply copy/paste, and I tested it out before sending it that it works on my computer in a Notepad and in a Wordpad file. I'm sorry if I misled you.
Anyway... keep up the good work, for I really like your posts and findings - but take care of your health.
